Is anyone else bitter about lack of family support?

My mom and my sister are very supportive, I’m sure my dad would be too if he was still alive. The rest of my family just doesn’t care and I really don’t care enough to ask them for support. My cousins were supportive at the time I was hospitalized but I’m not sure it was genuine concern or just to look good on the picture.
My uncle was supportive at one point, but he has cancer and it became a “who got it worse” at a certain point and I believe cancer is worse so I just don’t really care. Right now my uncle stole some money from my grandfather and I’m not talking to him, so I don’t really care if the rest of my family is not supportive.

I’m an independent spirit as well, just hope I can cope once my mom is gone.
