As a child I felt like a burden, so I tried to lighten the load by carrying not only my own weight but that of others. As an adult I now do the same, the same reason I have low self esteem, inability to make decisions, care so much about what others think, want to fix things for others but have no problems neglecting myself and guilt... we all know that one, I feel guilty for breathing air that someone else could use. I learned this because I was a burden as a child and up until today I would have said I no longer feel like a burden, but the reality is I act as though I do. I just didn't realize it until today.
