Hey everyone.
Have never posted in here because I've never had the guts to but I've read the thread for a long time.
Now seems as good a time as any to post. I hope that's okay!
I get this quite a lot, I'll either be really paranoid and on edge or be totally terrified of nothing what-so-ever. Spent the whole of a holiday sleeping on a sofa in the living room where my dad was because it was the only room I wasn't curled up in a ball crying because I was so afraid. And there was nothing to be scared of- I was literally afraid of nothing. I couldn't explain it to anyone- it was just pure terror that rushed over me and seemed to come from nowhere. Sometimes I find it helps just being around other people, other times the only thing for it (for me anyway) is to curl up in a ball and wait for it to pass.
Sorry that isn't much help at all but I do know what you're talking about so you're not the only one! And it doesn't make you pathetic or a wimp at all.
Please don't think that!
