Sometimes I just feel so stupid because I don't know as much as another person does I always struggled in school and had low grades in math and some other studies because of my mental illness issues.and my dad always made me feel so bad about myself for the bad grades he would belittle be because of them and it gave me such a confidence issue. It is very hard to get over this issue I have and makes it hard for me to get ahead and go to college because I don't know if I will be smart enough to make it or if I will just fail like my dad said I would.I need some self esteem advice to help me get over this large mental road block.
