I don't know how long I can keep going

i hate coming on here but I really need to vent. Just a meaningless shout into the void. I (24F) feel at my lowest, despite knowing there are still things I can be grateful for. In january, my dad died the most sudden death after being admitted in the hospital for just one week and a completely unforeseen stroke. I have no brothers so he was the only man in my house. After him, all the family drama that was already there has been amplified ten times to the point we need to completely cut off a close relative in order to just survive. And also my ungrateful selfish maternal grandmother who NEVER loved us continues to live with us despite knowing the man who took care of her is gone and despite having a son of her own (who is a deadbeat btw).

Apart from the family struggles, my job problems don't resolve either. It's been seven months since i transferred to my current office and I am yet to find a good commute. My office is 14 kms away from my home and it has gotten extremely mentally exhausting to go to work everyday because it seems my home is not within route of ANY pick and drop service. I constantly get thoughts of quitting my job but I know I can't do that because it took way too long just to land this job and especially because my dad is gone and I need to be earning to be prepared for any kind of problem that may land on us God forbid. But the commute problem is literally killing me at this point.

Yes I have no friends who I can share this with or help me. I have a boyfriend but he is literally caught up in his own shit from work and family all the time now. Despite trying his best to be there for me, he just isn't so I don't know what to do about that either. The only support system I had is falling apart and that is why I'm posting here. I don't know how long I can keep pushing through all of this I know there's no advice that can help I just feel so shit and there's not really much I can do about it except scream on the internet

Edit: thank you all for the supportive comments and appreciation.. but I'd like to clear a few things:

-Alhamdulillah due to my father's hard earned money, Alhamdulillah I am NOT in any financial crisis. Even with him gone, I am NOT the sole earning member in my family, Alhamdulillah. I should've explained it better that I can't quit because it was his biggest wish to see his children grow independent, and that in this harsh world, one must always be well prepared to fight ANY kind of circumstance for which money is really important and yes I'm still a middle class person.

-My office does not offer WFH to any of its employees. Yes I have tried facebook groups, a whatsapp group and the bykea app as well to find a decent ride to work. For some reason my timing and location does not match with anyone despite living in the middle of the city. Currently my going home commute is 1.5 hours long and I guess I have no choice but to get used to it.

Thank you for reading.
