Hi and welcome.
Therapy may help you.....it does help some.
I know it would not have helped me. I work the 12 Steps of AA. I also know of counsellors/therapists in AA, who still work the 12 Steps to stay sober despite knowing about counselling/having plenty of access to the services. AA is also free
Whatever you choose, you must do something different than you are doing now if you are going to have any chance of staying sober. You need a plan of action.
And no you don't have to reach rock bottom. The elevator stops at all floors - you are allowed to get off whenever you want.
Take care.
