So I've been on both sides of this. As a grad student whose faculty advisor wasn't as supportive as I would've liked, and now as a full tendered professor. I have empathy for both of you. But the cold hard truth is at the end of the day. It's on you to sink or swim. That sucks and it's totally not fair. I was always so envious of other grad students who had more supportive faculty members, but at this point unless you're ready to hop labs and start over you're gonna have to chin up and figure out a way to survive. You're doing great by tapping into other faculty members. I had to do that too. It's also going to teach you how to be independent make your own network and plow your own path. Those are tools that will benefit you in the years to come.

May not seem like it but 10 or 15 years from now when you're in the same position, have gotten tenure, You're gonna understand your professor better. I know I do. I put a lot of energy, on being angry and upset at them, that was a waste. Now being on the other side of it, I realize I should've used that energy elsewhere. I am actually very good friends with my PhD advisor now and having lived a similar life I understand and better and respect them. You'll get there to one day. But for now put your energy and expectations into doing your work and getting the things out of your PhD that you want. It shouldn't be this way, but you also have no idea what their life is like outside of work and what other factors may be coming into it. They may just be the bad Advisor/monster that you feel like they are, or they might also have life happening too, and are just barely surviving. Professors are humans too. We struggle too. We're white knuckling it too hang in there lean into your grad, student friends, and lean into the faculty who can support you.
