Hey Sunshine,
Glad your here. I have to agree with JT. Concentrate on yourself, getting you started. It will open some more doors for you! .
I know it must be very stressful living with your parents with him liable to "go off" at any time, but try to remember, no matter what he does YOU had NO control over it. I have only now begun to try to explain to my Mom that I have had to let go of my husbands actions and the worry about them because I can't change them. He is grown and will make his own choices. Don't know where you stand with your parents, but I have found it helpful in relieving the stress when we all get together. I don't feel like his actions "reflect" on me any more because she understands more now. (so do I)
Hang in there and keep posting. There are lots of great people here that have wonderful advice.......and are super listeners.
