Feeling Down and Out About Life

I am frustrated with so many things and don't really know what to do.

Career - In a funded masters and dislike current career entirely. Don't have enough funds for the career I wish to pursue. Feel as though I need to push through masters to pursue the career of my choice / earn enough. Feeling trapped by the cost of living and my education.

Finances - Being a graduate student pays nothing and I am in debt. Paid rent though!

Mental Health: I am my profs first grad student and he mentioned that I may be a bad fit. He doesn't really provide any form of encouragement. I work alone in the lab and feel isolated half of the time. see my supervisor for an hour a week. I cry in class occasionally and feel as though I am having a hard time with confrontation. Sleeping too much due to anti anxiety meds.

Physical Health: Feeling uncomfortable in my body. Gained weight and am not a huge fan of being not as strong as I used to be.

Romance: Feeling intimidated that my bf makes more than me and that it will impact the power dynamics of the relationship. i.e. more money means one person has more capacity to influence the relationship. Also I feel I have no financial safety net if he were to leave me / if something were to happen. (Saw my mum go through this, which is why I think this way).

When I tell my elders about my problems, they say, "Oh, it will work out". But it has been a decade already? If I am going to own a house / have kids or even have anything meaningful in life, I need to make more money. I don't want to remember my life this way.
