Dear Shelly,
Of course you feel like giving up after all thats happened in your life. Sometimes people dont know what to say to a person who has been through the mill. Its not that they dont care but maybe feel uncomfortable, but thats just my take on it. I'm always telling my kids. "Dont hang around people that make you feel bad about yourself". You dont deserve to treat yourself like that. Maybe you are your own worst enemy. After all that you still have it in your heart to remember the people that were good to you. I think you are amazing and stronger than you think. Don't give up PLEASE! I'm sorry I have no words of wisdom for you. Just Keep typing. I find its better than therapy in a way, because no matter what time of night it is there's always somebody there for you. Best Wishes.
