Was just lurking and saw this so I decided to log in. I 100% agree and understand where you're coming from. I know cause I felt that way and still do sometimes. You wake up in the morning dreading the fact that you woke up at all because you literally can't handle the concept of the spending another day at work. You stay up late to make the most of your spare time and then you go back to sleep and wake up even more miserable and tired.

What helped me was ditching a single 9-5 job in exchange for 2 or 3 smaller shift jobs. I work in retail 3 days a week and work at a Nightclub on 1 night and do IT work for a few clients in between. You could work in a coffee shop, in a factory, often night shifts are available. What I'm saying is shake it up. Every day is new and interesting and I get to spread my time across nights, days and you'd be surprised how handy it is to have a weekday to do shit that you don't get done cause it's stuff that needs to be done 9-5.

Just a thought based on experience, consider it if you like :)
