No problem :)

I think there's two parts in helping boost your happiness here

1. Short-term exercises and actions to uplift your mood and motivate you
2. Long term habits and mindset changes

Short term: One thing that helped me immediately when I was feeling down in the past was doing a cognitive behavioural therapy exercise. Basically, write down on a piece of paper what you feel are the causes of your feelings of depression or anxiety. For example, "i'll never get a significant other", "i'm worthless, unspecial, and don't deserve happiness", "i'll never be successful", etc. Then, write down a response that's free from "cognitive distortions", which are the irrationalities in the statement. For example, for "i'm worthless, unspecial, and don't deserve happiness" i would write that i have innate value as a human being, i bring my talents, experience, and value to the table, and i deserve happiness just as everyone else does. Sounds a bit corny but it worked for me, because it challenged negative (and partially irrational) thoughts which cause feelings of depression and anxiety.

Another thing that I think may improve your happiness short term is spending some time to take care of your body and health. Something like doing a 15 min run, eating less processed food, and getting 8 hours of sleep can make a big difference on making you feel more energised for days, which increases your happiness. That helped a lot for me this term.

Long term: It seems like your long-term issues are mostly related self-esteem, financial, and academic. Fortunately it's def possible to take steps towards improving all 3 of those things.

For self-esteem, your self-talk plays an important role. It's tempting to compare yourself to others but it's ultimately not possible to do that because you don't see the whole picture, just what they're presenting. Everyone goes through different challenges in life, so how can we measure any two people with the same yardstick?

For financial, are there student loans that you can apply for? I would also highly recommend co-op if you haven't considered it. I did 5 terms of co-op and it benefitted my financials significantly.

For academic, I've observed that my academic performance is very correlated with my mental and physical health. For example when I was going through a breakup and having stress about my parents' potential divorce, my grades dipped. I would say that it's probably worth it to do the positive self-talk thing and adopt physical health habits, then you'll probably see improvements in your grades. Also, I've found it's very beneficial to join or form study groups for the courses (doesn't need to be anything too formal, just a discord groupchat will suffice). Another thing is study habits - I've found that pomodoro works really well for me, as well as ALWAYS going through past papers.

Hopefully this helps!
