Will I be an Alcoholic.....

I feel like breastfeeding is all that's keeping me from tipping over the edge with my alcohol useage... I feel like my supply has been dropping and it makes me want to drink more because now I feel like a complete failure.....what do I do:( not looking for bashing just some advice....please. I'm scared if I stop all together I will drown myself in alcohol....what can I do to increase my supply and keep going...it's all I can do to make myself feel good anymore. I'm struggling with ppd and ppa as well...probably aiding in the want for drinking....
