Back, sort of.
The computer people couldn't replicate the problem with my computer in two weeks. Yet Ceilidh managed it within an hour. We think it freezes because it overheats.
In other news, I sent a letter to my psych describing how I felt and when he got it yesterday, he rang me saying I should go into hospital. He then rang the local mental health people to get them to organise admission for me. So now I am waiting on a phone call from them and they are taking their sweet time about it.
