What do you do to avoid being low on energy?

Long story short - I was brought up in a dysfunctional family, I was bullied in high school (despite graduating 3 years ago), I went to university for a couple of years despite still being affected by my dysfunctional family and high school bullies so not surprisingly I failed many classes, etc.

For the past couple of years, a normal day for me was waking up late (sometimes even at 1-2PM), I would eat lunch, go on the computer for a few hours, eat dinner, shower, go to sleep - rinse and repeat. I just felt like I couldn't cope with it anymore - my family broke me down, my bullies broke me down and I didn't want to live anymore.

However at the beginning of the year, I was able to get a job and a couple of months ago, I had enough money to finally move out of my parents' place. I am now living on my own in a new city (which also has the benefit of being away from my high school bullies), I have a job, I eat well, I sleep well. Of course it's not perfect which is why I am getting a referral to a psychologist next week to really focus on fixing my life but until I can meet my psychologist, what can I do to avoid being low on energy and really recover from my family/bullies? Should I just find hobbies?

I would appreciate any advice.
