Oh, honey *cuddles*
I'm sorry you feel so bad about yourself. I can relate
so much to this. Like, when other people say they hate themselves I can see that it's low self-esteem and realistically, they shouldn't feel so bad. But I genuinely feel like there's something fundamentally wrong with me, and I honestly am all these terrible things. But I'm starting to learn that that's what low self esteem actually does feel like; everyone else who says it feels just the same.
Looking at it objectively, what makes you such an awful person? What could you possibly have done that's so bad you deserve to feel like this about yourself? There's a list
here of ways to help improve your self esteem and such. I couldn't tell you if it's helpful but I'd say it's worth a go.
I know going to uni when you feel this bad about yourself is scary, but maybe it will be a good thing? If you can socialise with people and get involved in things, you might start to feel more positive about yourself. You're not 'inflicting' yourself on anyone; try to remember that they honestly will want to get to know you and a lot of other people will be feeling pretty similar. Have you thought about seeing a counsellor or something at uni?
I wish I could be more help. But sweetheart, please believe that even if you think these things about yourself, we don't. I think you're lovely and I'm so sorry you're feeling like this. Please PM me anytime you need to talk or anything. Take care of yourself, 'kay? xx
