I am so sorry things are rough for you but may I suggest you consider going to an inpatient rehab for the alcohol and deal with that demon first. I think you have so many things going on you are just plain overwhelmed.
IMHO if you keep drinking you will never be able to deal with the other dx as meds and alcohol do not mix.
Please seek help for the drinking first and know you cannot do it alone.
Look into AA. Here are a couple of links for you.
