Yes you do. You can start by deciding that you ARE worth more than you think.
You know what changed me some? Going to the counselor. She told me I am a child of God......and I deserve to be treated like I am. I had put myself down for so long, partly because of my past (or history with my parents, etc.) and partly because of what I did - I felt like I didn't deserve better than what I was getting because I am a bad person.
Now - I still feel horrid about what I did, shame, regret, an overall feeling of ickiness if I am asked to recall it - but I've been forgiven, the price has been paid and God still loves me.........
