Have you ever looked into getting therapy? And treatment for ADHD / depression - it certainly sounds like you have all the classic telltale signs as well as serious executive dysfunction.

And I can tell you- your parents DID fail you....

By allowing you to move back in.

If my child thinks I will EVER allow him to live in my house, playing video games for 8+ hours a day while he can't maintain a job.... Holy shit.

I can't believe that they allowed you to move back in, didn't ask you to contribute you the household bills, and have done absolutely nothing after you've done absolutely nothing consistent to better yourself or your situation in all that time.

My man- ADHD is hard. Adulting is hard. But you've literally admitted that you've wasted almost all of your 31 years - and it hasn't occurred to you that you DEEPLY need medical care to get to the route of your serious mental health issues ...

Please. Get up tomorrow and start making phone calls. GET TREATMENT.

You are never going to get better or have any kind of life worth living if you don't.

My brother died last year at 49 from untreated high blood pressure and he literally lived your exact life that whole time. You don't want to end up like he did.
