Need advice: feel completely overwhelmed. What can be done?

I'm a recent MBA graduate looking for an entry-level job in finance. Right now, I'm barely getting any interview calls, and my situation keeps feeling worse.

My parents aren't pressuring me to get a job immediately, but there are constant comments that increase my anxiety. My father will turn 70 next year, and he often says that once my brother (30) and I get married, his responsibility will be fulfilled. I completely understand where he's coming from because his health is declining, but I want to become financially independent before marriage.Because of my family dynamics, I'm honestly scared of marriage. If I ever marry, I want it to be someone who genuinely loves and respects me equally.

My mom has her own mental health struggles, so she's not emotionally available. My older brother keeps telling me I'm not doing enough and constantly pushes me to do more, but he doesn't seem to understand how difficult the current job market is or everything else I'm dealing with. Every conversation with him leaves me feeling more pressured.On top of that, my maternal grandfather lives with us. He's quite toxic, and since his room is on the same floor as mine, I end up taking care of many of his daily needs.

Emotionally, I'm also struggling because my boyfriend still can't decide whether he wants a future with me. He keeps delaying the decision, and the uncertainty is exhausting.Recently, I was also diagnosed with thyroid issues, so my hormones are all over the place. Between the fatigue, stress, and everything else happening, I feel mentally and emotionally drained.

I honestly don't feel like I have anyone I can talk to, so I wanted to ask for some outside perspective.

Is the job market really this bad for fresh MBA graduates, or is it just my perception? If it is genuinely bad, how can I explain that to my brother so he understands that I'm trying and not just being lazy?

What would you do if you were in my situation? How would you navigate all of this without completely burning out?

I'd really appreciate kind and honest advice. I'm trying my best, but lately it feels like everything is happening at once.
