I can't loose weight...

Ok, i just need somewhere to vent... Because i dont know what to do... I am trying to lose weight... I have been for a long time.. And no matter what i do the number just keeps climbing... I am 5'6 and 220ish lb.... When i started High

school i was 160.. A little chubby but still pretty. And now that i am a high school alumni this year i weigh almost 230... I tried everything i could i stuck to diets for months, lived a healthy life style.. Stopped snacking and ate clean healthy foods and excercised for multiple hours daily... And yet the numbers climbed... I want to loose weight so badly because i know it will boost my confidence and make me more productive but it just isnt happening. And the more and more that number rises the more and more worthless i feel...the only time i was happy with my body was when i was anorexic due to ADHD medication.... I try so hard but nothing good happens.... Its to the point where it doesnt even feel worth it to get out of bed.. But i still do anyway... And with me being strung along with my job and then being fired due to covid... It just makes me want to give up.... I don't know what to do....
