Overwhelmed by life

Flair is ''seeking empathy'' but am quite open to advice and constructive comments.

I'm now on 30mg of Vyvanse and have been on 20mg for the past 3 months.

Here's my current life situation :

Canada.
29M turning 30 in september
Two years to go until bachelor's degree completion : Nutrition science.
University is 10 hours from home ; I move back and forth twice a year (every summer).
Currently back home, living with a friend for the summer (600$/month).
I work as a security guard for festivals and all kinds of events, but there's not enough work to do full-time every week.
I've applied and keep applying for different kinds of jobs but am not getting call-backs so far.
I've created a website, printed flyers, posted paid ads on facebook/instagram for services I offer like window cleaning, pressure washing, dog walking, car cleaning and tutoring.
There's 4k on my credit card I'm trying to clear off as fast as possible.
There's 24k on my student credit loan (from the bank) I'd like to pay off at least a little before september comes.
I'm trying to workout and enjoy my summer at least a little and spend time with friends.
Making videos on youtube is on my mind ; which speaks to me more than any student summer job.

All of that being said, I'm lethargic and depressed, overwhelmed by the pressure debt is putting on my mind. Overwhelmed by the choices I need to make. I feel alone. I compare my life to an ex's, I feel like a loser.
I'm not moving forward much because I'm feeling depressed, which makes me feel even more depressed.
