Stress on top of stress !!

I been stressing myself my whole life .. like literally I stress about everything I try my best to keeps as much negativity away from me but late at night is when it hits me that I been a failure that Im not doing anything to stop myself from being a failure I'm currently 20 years old and I'm not done with highschool ( Damm you still in school yeah .. yeah yeah ...) I know I fell back my sophomore year because of personal problems... Like some traumatic shit and I get it that's not something to blame but i couldn't focus on school while shit was happening at home ...and now without my highschool diploma I can't seem to find any jobs ... I want to make myself useful and help my parents out with bills and things like that but I can't do much ... And I been carrying all this stress in my shoulders and I just want to stop myself from feeling this way .. .. i just want to be done with everything !!😩😭
