What you have survived shows you inner strength. A strength that you may not accept but it is there. Life is not fair but you as a person offer much to everyone here. Take a breath bask in the sunshine and remind yourself you have endured and survived.
Find a place to talk so you can laugh. Laughter helps sooth the pain. I bet if you open up people would embrace. I have learned there are many who are not compassionate despite how they portray themselves to the outer world. But there are many compassionate people who will be there for you.
Do your best and life may surprise you. You deserve a break.
