As other people have said, people come before anything else, which is why I'm back on here writing to you and trying and respond to your first post instead of doing other things. I don't feel obliged to, I want to.
I used to think the same as you in that it's a weakness to ask for help. I hated doing it. I used to think you should be able to cope with things on your own. However, circumstances around me changed, and I couldn't keep up. I don't want to go into here, because this isn't about me, but I eventually saw that asking for help is something that should be admired. It was so difficult to recognise that I needed support, because I couldn't see it myself. The reason I couldn't see it was because I was so wrapped up in what had actually happened, that I couldn't see the bigger picture, and how it was affecting everyone around me.
It takes an awful lot of guts to ask for help, especially if you're an independent, likes to help others type of person, which you appear to be.
I'm sorry that I haven't, nor anyone else on here seems to have been able to help that much. I'm not saying that you should go and get professional help, but what I am saying is sometimes you need an outsiders perspective. Don't close yourself off from people, I know from experience that it hinders rather than helps - even if you are a very private person.
Your first post says to me that you want to try and change your opinions of yourself. Now, you need to put the effort in, and if that doesn't work, then in my opinion, you need to have a chat with someone who knows a little more about this type of thing than any of us do. Nothing will change though without a lot of hard work on your part. It's got to come from you, and it'll be hard, but you've got to have the determination to get through it. Have faith in yourself and take care, x
