The road to recovery is never an easy one, and it is definitely one you do not want to walk alone. Alcoholics Anonymous (AA) comes to mind. I know a few people close to me who have taken the AA 12 step program, and who say they could not do it alone; i.e. without a sponsor and a support group.
Addiction is a difficult battle to face on a minute by minute basis, and you can be just as addicted to hating yourself as you can be to that next fix you need. It is debilitating, life-destroying and saps all the energy you have within you. Your road to recovery will help you get the love and support you need to learn to love yourself no matter what.
