Depression, alcoholism. We can't resist.

My depression is two phased. for a week I am super energetic and hyper active, next week I don't even feel like getting up from bed l. This cycle continues and in last 2 years it has become terrible and affects my work and personal life. Earlier I was an all rounder with 100s of hobbies and now from past 3 years approx I only enjoy drinking. In last two years not even a single day has gone when I have not drank and the capacity is increasing month by month. Another major problem is that my spouse is also alcohol addict. We both have had a rough childhood because of family disturbances. Please suggest as we both have tried alot but of no use. We don't drink during the day even if it's an off from work but at night we can't resist.
