I don't know about anyone else but, I have difficulty thinking of myself. I always help others, regardless the strain it puts on me. Not saying I'm perfect, merely very selfless.
I have difficulty thinking of myself because I feel dirty when I do. I am trying so hard to think of me but, I have a low self worth. My father made aware at a very young age, that I wasn't worth squat. We learn as children, a lot of the things we use in adult life.
I've sat and thought for a long time, how to put into words, how difficult it is to shake the low self worth. I think I've found a way to say it so others may understand myself and other people who have this problem:
Trying to unlearn being taught you're worthless as a child, is much like unlearning math that you learned in school.
