Struggling with Sleep and Productivity

i often find it really difficult to wake up at the same time every day, and it's harder to wake up before 2pm. sometimes i manage to wake up at 9am for a week, but then i play videogames for 10 hours straight, end up doing an all nighter, and ruin my sleep schedule. i have repeatedly done this, even when i was in school. I'm out of school now and unemployed, but also my sleeping habits and gaming addiction reduces my chances of working on my portfolio and getting a job. sometimes i am not sure i want a job. often times when i start working on my visual effects portfolio i get bored and switch tasks after an hour. if this new task is videogames i don't do anything else but videogames for the next 4+ hours. if it's not videogames, then it's watching youtube or drawing. neither of which is portfolio work. sometimes i wonder if i should just try to get better at art and sell art online, but i also don't think my art is where i want it to be to where i can sell it. there are many days that pass where i do not feel that it was a very productive day, and i get upset at myself for not doing more, and attempt to compensate by staying up late attempting to work on my portfolio or by drawing. getting anything important accomplished without external stressors is difficult and requires focus that i cannot supply on a daily basis. i sometimes wonder if i have adhd or autism, or both. it is a struggle 😓😓😓
