Radien... please don't give up on yourself. If for no other reason consider the impact you have on your sister as a role model. You need to be able to walk your talk if you are going to advise her about her choices and actions. You are probably the most significant influence on your sister right now. That can be a huge pressure especially when your father seems pretty set in his way of thinking about professional help. It can also be a huge opportunity for you and your sister to overcome those challenges that you face.

I am curious to know how your father is responding. Please keep us posted.

Wishing you and your sister well.
