Lost the ability to do any productive work?

I am a male ,31 years old and have been jobless for 14 months. Still i don't feel like studying anything for it to get a job, i overthink at night but i don't do anything, usually i masturbate then i feel weak, then i drink beer and think from tomorrow I will study but i dont.

Later i realised when i had a job for 5 years, it was just because managers were lenient, i hardly used to do anything and got fired. Before that in college also i remember i hardly used to go to class.

All i do is bed rotting, overthinking imagining myself doing everything in future but in reality just masturbating and then regretting.

Even if i try to sit and concentrate i hardly am able to.

I don't know how to restart ? Kindly suggest if you have any solution!
