Did I do the right thing?

I am a twitter user and last week I had a situation where I hope I did the right thing.
A user I follow posted a link to her blog which said that (amongst other things) that this was goodbye. Now being a mentalist I wasn't sure if she meant goodbye to blogging or whether she was not safe. I tweeted back that I was worried but didn't get a reply. Then another user tweeted he was also worried. Anyway, after tweets back and forth and the fact the tweeter has a daughter from the info I could gleen about her, both myself and another tweeter phoned a U.S police department to do a welfare check.
They did the welfare check and all was OK, but I felt an enormous sense of guilt afterwards - Did I do the right thing?
Was I interfering? Did I read too much into what had been posted? I know if I had the police turn up at my door I would probably be really pissed off, especially if I was suicidal.  I don't know, it felt like the right thing to do at the time, but afterwards I felt I had made a lot of fuss about nothing.
I was expecting this week to be relatively quiet at work but it has turned out to be majorly busy.  Technically my contract ran out last Saturday but Ski School aren't worried by that.  However, the office is totally disorganised.  I won't bore you with the details but I am pretty exhausted and today couldn't even lift my head up off the pillow.  I telephoned and lied, saying I was vomiting and had an upset stomach and that I really couldn't work.  My boss asked what they should do.  I held my temper and did not shout "I don't fucking know, you're the boss".  Later, they phoned me (repeatedly I might add) and asked if I was OK.  I said yes and then was told that if I am not in tomorrow then "we are in the shit".  So now I feel enormously pressurised and have also found out that not only do I have to do my job, but on top of that I have to teach as well, plus babysit a kid until 5pm.  So I will be working 8 a.m. to 5 p.m. without a break and then on to my other job which is half an hour at the end of the day closing up a shop.
I am totally drained.  I haven't even booked my flight back to the UK yet, or started packing.  I managed to clean my apartment yesterday and I have to say it looks cosy and back to how it should be.  I have ignored my ex boyfriend (I can't even cope with him at the moment) and told him I would see him tomorrow (in case he had any ideas about coming round here).  I can feel myself sliding a bit but have no time to go and speak to anyone, just to let off some steam and calm myself down.
I think I need some chocolate.

Am I being oversensitive?

OK, OK, so I have felt better today until the afternoon and an email from my brother via facebook. Then I went through anger, tears, resignation that I am crap etc, etc. It all stems from a fb page I did as a laugh for my best mate who was screwed over by her boyfriend big time. He also stole some inheritance money of mine which I had lent to my bezzie mate for mortgage arrears. Apparently, well...read for yourself:

If this guy is as much of a dick as he appears to be then I wouldn't give him the satisfaction of thinking that you give a toss about him enough to even think about him.

If he's taken money then small-claims court him and be done with it, he'll have a CCJ then. If he hasn't then aren't you in danger of harrassment here? If people looking at your [work] stuff also see that there is an [me] waging a hate campaign on someone very publicly online then I'm not sure that sends out a good message.

Patronising c word is all I can come up with. My brother is 3 years younger than me by the way. I mean, yeah I know I'm mad but he could be a bit more sympathetic towards me, or is that me being selfish or something. Sent him a snotty email back:

Thanks for that. At least my Psychiatrist will get his moneys worth tomorrow. It's not a "hate campaign" and why is it OK for some people to say horrible personal stuff about me yet I am not allowed to protect my best mate by telling the truth. If he wants to sue me he can try, we'll be quits then. But maybe you are happy with him pissing Nanna's hard earned savings up the wall. And yes I know I am being oversensitive, I have ATYPICAL DEPRESSION, Wiki it.

Me
(Not sent in anger, sent in I'm tired of suffering this horrendous illness and just about functioning but at least J looks out for me and have supportive friends on fb)

Just to explain, my older brother sent me a horrible, horrible email at a very emotional time calling me horrible, horrible names and accusing me of things I haven't done or relate to the person that I really am. Added to matters which finally got me sent to a psych clinic. He said he had sent it in anger. He said he had held a gun to his head and hadnt thought of me. Since then everyone has been on his side totaly and he seems to be allowed to say anything about me and accuse me of things that piss him off. None of us except my younger brother were told about the gun thing. Now I am more open about my depression (everywhere except where I live and the immediate people around me). But not one member of my family flew over to see me in the clinic (I was there 7 weeks). Not one sent me a card or letter or anything of support except my godmum. My sister phoned once but most communication came from me outwards. My boyfriend was and still is shocked by this and (poor thing) he had all the stress and weight of this with no support from my family. Just me, him and our GP.

I have calmed down now but am still very sad. What pisses me off is there is always someone criticising how I react or how I feel towards something that I no longer trust my own feelings or who I am.

I am actually really looking forward to my Psychiatrist appointment tomorrow. I really need it.
