It sounds to me you and your family have issues that go far beyond your being transgender.
"They just are giving me things and sacrificing their own lives for me."
"my mom has paid for everything such as hormones, clothing, orchiectomy, and even partaking in the transition themselves."
So they are investing in you their time and money, "sacrificing their own lives" for you, and that's not enough?
"The common theme seems to be, the emotional love/connection is often not there. It is very draining and exhausting..."
I wonder how it must be for them, sacrificing their time, money, and lives, and you not being happy?
No one can give you happiness. That's on you. It surely must suck not to feel loved by your family, but my god, they are sure seem to be trying hard to help you.
Earlier in my life, in my 20s, I went through drug addiction and prison. I blamed the cops, the laws, the courts, and society. Eventually I figured out exactly where the blame belonged - on me, and the choices I made. After I got out, I got clean, rebuilt my life, put myself through graduate school, and built a career.
Now in my 50s, I am choosing to transition, even though it may cost me my children, many of my friends, and my career. It's tough. I was in a loveless marriage for years, and now that I am separated I spend many a night alone wondering what the hell I am doing. Slowly, I have built new relationships, and have a few precious friends that accept me for who I am. You can do the same. I think you will be surprised how much strength you have if you believe in yourself.
In my humble opinion, I think you would be best served by focusing on the support you get, and taking ownership of the choices you make. You are responsible for your happiness, no one else. Be someone that people want to love.
With kindness,
