I don't know where to start but basically I'm a student (21F) living in my parents house and having online classes. I've been feeling unmotivated and it's been hard focusing on my college work since everything at my parents house is complicated rn. My grandparents are my neighbours and one of them is completely dependent on my family to eat, shower and do daily tasks and my other grandparent suffers from mental health issues (depression, anxiety and obsessive compulsive disorder) so she can't handle living with my grandfather alone or else she has anxiety attacks and starts crying because it's difficult to deal with my grandfather as he's constantly asking the same questions and saying the same things. So my parents (mostly my mom) have been helping my grandfather doing daily tasks and hired someone to help in the morning but this isn't enough. On top of this, my grand-aunt also lives with them but was recently diagnosed with stomach cancer and since last week is staying at the hospital where she had her stomach removal surgery. She always helped my grandparents a lot but she'll come home next week very weakened and will need help doing everything (she can't even walk on her own). So the house will be full with two family elders totally dependent on someone and my grandmother severely depressed. My mother is exhausted and my brother (a recent graduate unemployed because of covid who had to comeback to his parents house and is also depressed) doesn't help a lot by having constant fights with my grandmother which results in her crying all day and consequently making my grandfather worried as well and more tiresome. I'm in the middle of this. I've been here for 3 weeks now and I have the possibility to go to the city where my uni is (despite only having online classes) to live with my friends and be with my boyfriend. The thing is my room in the other city doesn't have furniture so I need to buy a desk and so on and that also stresses me out. But if I stay here I don't know if my mental health will get worse. I've been staying over my grandparents house since my grandmother doesn't want to sleep alone with my grandfather. So me and my brother created a rotation system where I stay here one week and he'll stay the other. This week is my turn and I feel completely exhausted, unmotivated. It has been difficult getting out of bed so I feel like I can't help much around here if I also get depressed. I've decided to go to my university apartment tomorrow but my parents are trying to convince me to stay. They've said that I'm being selfish and that I don't need to go and that I'm needed here to help them and my family. I feel completely confused and divided cuz I kinda agree with them and feel like I'm being selfish but at the same time can you ask this amount of commitment from someone who has an historical of mental illness? Who is almost finishing her graduate course and doesn't have any prospects for the future during a pandemic? It's just that I already feel lost and feel like I need to have a lot of self commitment to face my own insecurities and my insecurities regarding my future and with this problem adding up it really doesn't help.  I don't want to be depressed again, not after so many years of fighting. I know this family environment is not good for me, I mean, I already had problems and trauma with my parents (they were/are abusive parents and I feel much better if I get out of their house). The thing is, if I go, is there any way that things will be ok back there? What can my family do? I also don't want my mum to be exhausted because 
I'm sorry if my English is bad or if you didn't get anything from this. Ask me if you want. To anyone who reads this: thank you!
