Irate, Mentally Immature, Depressed, Unable To Control Emotions, Supporting Family From Early Age. Treatment?

hi doctor, i feel like just to hate myself now a days. reason is now i get very irate and have no control on it and this is affecting my dear ones very much. they think that i am a good person and they forgive me every time and this is a limit now that i even cannot say sorry to them, because this situation had gone much worst now. i think i am mentally immature and i think i don t have ability to handle my relations with my friends and family. please suggest me something so that i should stop all these non sense things. about myself : i am a 25 years old guy who works in a private firm and i support my family with my earnings. i had never been in a relation with any girl in the past, i know i have interest in girls but the age i started working and supporting my family was a bit early and i never distracted my goal to support my family. my father left us when i was 10. and from that day onwards we became very poor, nothing to eat, no roof to hide, and lots and lots of problem. i think to do something good, but it goes opposite. i was in a great depression in past around 3 to 4 years ago and i think i had never came back normal. please suggest me.
