been hella depressed lately

the past few weeks/months have been utter shit. my grandma is back home from the senior home where she was for rehabilitation from her heart attack. it is a relief that she seems to be just fine rn and i'm extremely happy that that situation played out as well as it could've. the biggest problem i've been having lately has still been familial. for some reason, no matter what i do, it's never enough for my family. i've been struggling with this idea forever, and even when this summer came around and i've been having to drive my grandpa around a fuckton and helped my grandma out too, no one thinks what i'm doing is enough. they act like my life needs to revolve around their needs but i still have a social life of my own to take care of alongside a job that i need to work in. they act like since i'm at home for the most part i don't work but in reality i work quite a bit and the work i'm doing is fairly important for the company i'm at. there's just something about me that makes me an easy target for hatred i feel. no one in my family besides my mom and my brother seem to think anything of me for the most part. my grandma does sometimes, but everyone else seems to not believe that what i'm doing is good enough for my aging grandparents. apparently donating entire days to driving them places and doing their jobs for them isn't good enough because i don't spend the nighttimes with them cleaning up after them and doing shit for them all throughout the day. it's not my fault that my life is more complicated than you think. i just don't get the whole point of me being the bad guy in this situation after all i've been doing for them. i got into an argument with my grandpa after he tried making me (note the making me i say, not asking) doing his job for him after i got off a long day of work that day. i'm woken up from a nap i'm taking and he says "we're leaving in 15 minutes" and i say no, sorry i'll be able to do it in the morning. he then gets really upset and says no we're doing it tonight and i say i've been working all day and then he says i don't give a shit what you've been doing i have too. he mowed the yard and while yes that is work i don't think he has a right to say whether or not that means that what i'm saying isn't worthy of saying. he's always done that and i'm finally starting to grow the balls to stand up to him. anyways, after all's said and done he says "i'll do it myself" and i say no we're doing it in the morning. he goes to the living room and i go to my computer. i get really frustrated and decide that i'm tired of being treated like shit so i go to the living room and tell him i'm not his slave. he says "i don't want to talk to you, you're the most selfish person i know" as if him using me this entire summer hasn't been more selfish than me being tired after going to work at 6 am and staying there all day. so at this point he's already set me off and we get into a big argument about how i feel like he doesn't treat me with respect and my brother backs me up and that felt really good. he didn't understand why i felt that way and i couldn't get it through to him no matter how hard i tried. at this point i feel like it's impossible to gain his respect so i'm done trying. if he wants to treat me like an employee rather than a grandson, so be it. i'll be an employee. it's so frustrating trying to be like him in some ways yet he just always finds a way to bring me down. however, the morning afterwards (which he tried leaving without me rather than waiting for me to wake up and get out of the house) he said he appreciated my help, which means he at least got something out of our argument. i've been trying my hardest to be there as often as i can for him because i know he doesn't have a lot of time left but i can't do everything everytime he needs it because i have my own schedule too. it's not like i'm only existing to be his lapdog. he never asks anyone else for help, only from me. he says that my brother takes out the trash yet he's always done that, that isn't something new he does. compared to me, where i work  3-5 hours a day coding/researching, drive him 3-5 hours a day, and sometimes fix the vending machine and that can take about 2 hours depending on the day. those are exaggerations but they still hold true for just how much of my time i have to donate to him in order ofr him to be happy. i can't do things without wondering if my grandpa will ask for me to be there and drive him somewhere. it's incredibly frustrating. i wrote a draft of this post about a week or two ago and i was in a much worse place then mentally. i'm doing better now, but i still feel like i'm not enough for them no matter what. i know that the entire family thinks i'm useless and do nothing for them but if i actually did nothing no one would've seen my grandpa the entire summer. if i got an "actual job" according to my grandpa what would he do? he'd be stuck here. yet he doesn't ever go to me for anything other than doing shit for him, never anything else. if it is, it's asking where my brother is. i'm so fucking tired of being an extension of my brother. i need to move out.
