I can understand the guilt, but remind yourself that you are not choosing this. You didn't ask to be trans, you just are. You can deny it and hide from it and try to push it away, but it will still always be there eating away at you and years then decades of your life might slip away (like it has with some of us) where you will have not been the person that you are supposed to be.
I have learned after 6 years of marriage to woman with borderline personality disorder that I can't make other people happy and that it isn't my job to make other people happy. Of course there are things you can do that you know will please or displease people that may indirectly lead to happiness, but that isn't what we are talking about here. Overall, people have to find happiness in from within. This includes yourself and the rest of your family. While your transition may have made things a bit turbulent in your family's lives, it is their own hangups, biases or misunderstandings that may be causing any strife.
Also, transitioning is hard, for everyone involved and there are HUGE adjustments that very likely will take many years to fully resolve themselves. Don't let it get you down. I came out to my mom. She wanted to make sure that I knew that she would love me no matter what, but she is confused and clearly doesn't understand what I am going through and is a bit alarmed. The last time I talked to her, she didn't even want to talk about it. It is enough for me to know that she loves me, though. I will attempt to help her understand what I am going through, but at the end of the day if she never does, that is just something that is out of my control.
Hope this helps...Hugs
