Improve your "Self Esteem". In other words, take pride in yourself. If you can't be proud of yourself, who do you think will do it for you? People only care about those who care for themselves.
Why did you lose it?
Sounds like the eating disorder may have caused you some anxiety. You may find it valuable to talk to a therapist and he might suggest some techniques or medications to help. <br />
If you are committed to figuring this out on your own, I'd suggest trying some deep breathing or meditation techniques. And perhaps most valuable, would be to find something you really enjoy doing by yourself and using this as a starting point.
Peace of mind has to come from within a person. Others can affect our lives whether good or bad but we do have control over our emotions and feelings. First recognize that it is alright to be alone and take this time to think on what you enjoy as a solitary pleasure and things that are healthy and good for you. Do you like to read? Pick up some books at the library and read something that brings a smile to your face. As you have had two relationships that did not turn out as you wished, it might help to read books about relationships. Take your alone time as one in discovering who you are and the good qualities you possess. Any time you feel doubt in your mind say to yourself that you want to be happy and content. As you continue to practice this you will find yourself feeling better and empowered. Peace,D.
I believe that feeling stems from being happy and content with yourself (as opposed to by yourself). Maybe you should ask yourself what changed in that area.
Do you know that you are created in God's image?and that He loves you and has a PLAN for your life/a purpose that He wants to show you? But, you must come to Him and ask for forgiveness of your sins. He gives that freely and willingly! Then ask Jesus, God's Son, into your life as your Saviour, your Lord! For it is only He that holds the keys to true life.
I am happy for you that your faith has helped you to find peace. But I choose to take personal responsibility for my life and be more proactive.
