STEP AWAY FROM THE DRINK
seriously there is no help or escape in the bottle - just another problem to replace your others. If you even thing about heading down that line dunk all your booze down the sink! (or toilet or bath - but dont bathe in it!)
First stage talk to the university - in particular talk to the department head of the department/subject that is your core area of study. Universities are a bit more lax and flexable to personal situations so talk to people - don't just deal with the offical channel (that only works according to the book). If you have an interst and a keeness to learn as well as good mind you might be able to talk your way in.
Also remember that there is always another way through things - try your best at one rout and if that fails pick yourself up and follow another (often the picking yourself up part is the hardest part).
Also (and this might sound silly) but speak to your husband or a friend (heck speak to an online friend if you need to) but speak to someone - stay in communication with your thoughts and feelings (should do this with husband always). Not to run a constant depression trip but just so as you keep things outside and not bottled all up inside.
You will get through this

!
Good luck!
