Thanks for all your replies - they've really been useful, and I'm sure all of them will help me in making my life better.
I'll probably use Anxiety Free and Belief at the moment as I've already got them, as well as positive affirmations regularly, because I realised I used to be quite negative and unprepared to accept people liked me incase they didn't and I got hurt again. Although I'm not expecting everyone to like me, I'm sure these wil help me be able to take rejection easier and stop unnessecary worries over if I have annoyed someone etc.
In reply to Hoss's question about what other positive changes I've recieved as a result of improving my self esteem:
I've started eating properly again. I used to go days without having a proper meal but now I always make sure I have one. And I eat lots more fruit.
I'm generally more interested in my health and have started an exercise regime.
I find it easier to get on with things, and I no longer lay in bed untill late in the morning agonising over all my worries.
My sense of humour has returned.
Good Luck in increasing your self esteem - these tapes really help. Just keep at it, you'll soon start to see the changes.
