I know how hurt feels. I've been through so much in my life, mean people saying horrible things, death of loved ones, messed up family. I got through it because I asked for stength from God. God is always there, even though we cannot see him, we can feel his presence.
Once you start to pray and ask God to come into your life and lead you to where it is he needs you to be, you will feel him, his Presence, you will understand things. Your emptiness will be filled with the Holy Spirit. God is the one true friend that will never let you down, He is always there. Knock and the door shall be opened.
Believe in yourself, believe in God and his power. Ask yourself what do I like to do, who am I? If you do not know, think of the things you liked as a child. Riding a bike, bowling, fishing, swimming, and just go do it. Find something for yourself, separate and apart from anyone else in your circle. Do something for yourself, get involved in it.
