You CAN be strong enough to do it, you just gotta want it with all your heart and soul. It helps to have a supportive person or persons, family/friends, as long as you have someone 'in your corner' to support you. If it's not family or friends, maybe counseling could help. I go to my addiction counselor once a week for an hour. It helps me a lot to be able to vent and get her feedback. Give it a try. It can't hurt.
