God Bless You & God Loves You my Friend. I find that the people who suffer the most in life are the biggest blessing to others...that includes you. You are valuable! You have so much too give. Don't give up. I am praying for you. You are fearfully and wonderfully made by God. There is no one else like you that can contribute to others like you. May I suggest some things:
1) Keep a journal. Write your feelings out.
2) Seek out a close friend you can unload on confidentially that will listen.
3) Stay away from a lot of negativity. It will only bring you down more. Don't watch a lot of news on T.V.
4) Find something in every day to be grateful for....big or small.
5) Find someone to be a blessing too. Write a card to them, make a phone call to them...there's a lot of lonely people in this world.
6) Laugh and laugh a lot. Love and love a lot.
7) Get a pet if you are able to care for them. They love you unconditionally and give so much love and you can love them right back.
I hope some of these help. Hugs & Prayers.....
