I looked around for a while, this is probably the best link I came across. I could use some more work in this too.

A therapist can totally help you with this ,Trippin is right. You can still work on it on your own too, there are no rules about any of this stuff. I like how they break down self esteem from self acceptance in this article. I'm learning some new stuff myself.
No pressure to use any links I put here, I just find linking to material in topics like this useful, as it can help us with somewhere to start and stuff to think about. Because these topics are complex.
If you google mindful self acceptance you get some really interesting articles, but yes they mention buddhism so I will refrain, but the concept and ideas in them are soo spot on I think.
