No, you don't 'need' to hit a bottom before asking for help. My bottom was mental. I knew I was drinking too much and was losing the respect of my kids, not to mention my self respect. As far as recovery goes, many here have recovered just using this site for help and information. Private therapy may be a valuable resource for you. I see an addiction counselor once a week and she's been very helpful to me in staying sober, as well as other parts of my life.
I'd say go for it. Get a counselor and listen to their advice. I hope you can stop drinking before you do hit a bottom and/or do damage you can't undo.
