It sounds like you are under so much stress. I bet it feels like you have the world on your shoulders. My only recommendation is maybe setting some boundaries with your family.

I wish I had good family advice, but I was raised in a dysfunctional family and the only way I could cope is to just ignore most of my family. The only person that is important in my life is my spouse, and even at that I have constant fears she doesn't love me and would abandon me.

My only suggestion is to make some time for yourself and put your foot down when things get too much. My family used to use me a lot and they hardly helped me when I needed it. After I started setting boundaries my life become better and I felt better about myself. I hope you can find a way to get balance into your life.
