Improve my self-esteem

I think I might be someone that most people would consider outwardly to have good self esteem but sooo not true. So Im working on it – trying to do things to make myself feel stronger, increase my confidence, move outside my square etc etc etc. Its funny Im sure people have said nice things to me, actually I am 100% positive they have quite often but at this moment I can’t remember one but I can remember every single comment or look that wasn’t so nice from the past 10 years – isn’t that amazing and the funniest bit was they came from people who didn’t mean anything by it, weren’t being malicious and the other ones from strangers who I honestly couldn’t care less about but the comments still stick. It is these comments that I try with all my ability to avoid and hence doing this decreases my self esteem because I eternalize them even more. What you eternalize becomes real – mabey not to anyone else but to you – the brain works in funny ways usually what you tell it believes and doesn’t have the ability to differentiate the truth from lies. I need to learn to distinguish between the truth and the lies I tell myself. I know this is a long process but I am determined on getting there – I want to be able to shrug comments off that I know to be lies, I want to feel worthy and not care what anyone thinks.
