How To Improve Self Esteem While Having ADHD?

Hi. I would like to better understand why I am so emotional and why I overreact about everything. I have ADHD which I m not sure if that has anything to do with it or not. Also, my self-esteem is very low and I would like to know how to increase it. I often think that everything I do is wrong and beat myself up over everything. Sometimes I feel an urge to cry and I get upset for nothing. I take things both very literal and personally and I hate it. I often think negative and bizarre thoughts about things that would most likely never happen. your average person wouldn t think of these things like I do.
