I genuinely hate members of my family.
Why do you hate members of your family?
I have some deep psychological complexes about my immediate family.
Sometimes getting along with family can be difficult especially if you are going through things yourself. You should find someone to talk to about your issues first, though.  When you have a handle on that, you can work on ways to get along better with your family.
What should I do to get along with my family better?
There's an old saying that you can't hate someone if they really know their story, so as long as you are feeling up to it, I would say that you should just spend time with your family and really listen to them.  When you understand what they feel inside, you will be able to relate to them much better.
