33 no self esteem, friends, and more...

I ŕeally dont know what to think of myself. I have to tell myself im 33 but i feel i act like a toddler. I feel so weak i cant stand up for myself, my voice is shakey when i speak, Ive always been isolated and avoided in school even when id try to make friends. I just feel pathetic, i just feel invisibl. I wish i had a commanding presence, i wish i were strong, i wosh i had friends that loved me and my family as well. I hate my existence. I wish someonebesides my kids loved me and wanted to spendtime with me. I dont know whats wrong with me. I already go to therapy ..idk whay else to do.
