<human>: Can you give me a shortened version of the text?

Long story short: We have been through a tonne together, basically every relationship problem you can think of. We have broken up four times over the past four years since we started dating in grade 12. The last time we got back together was August 2013, and our relationship has been so awesome since then.

NOW:

My girlfriend suffers from serious depression, and I am there for her even when she doesn't want it. She dropped all of her class this semester because of this issue she has been having. I am studying engineering, doing well, huge drive and motivation... basically a huge turn around from a few years back. 

I also liketo do drugs, not often, but a couple times a month for sure (MDMA and cocaine). She is fine with MDMA, but cocaine is a huge no-no, the last time she found out I was doing blow, she gave me an ultimatum, which I questioned and found very unfair. I did however agree to it, because I did not want to see her go that day. Two days ago she saw me with a key shoved up my nose and shit hit the fan. She still loves me, but is now not talking to me until she consults her therapist. 

I guess what I am asking here is if I should take some action... do I wait until her therapist "guides" her through it? If she comes back to me, I will have to tell her that I am not a junkie, problematic or unmotivated( ALL TRUE ) I just do drugs once in a while with the boys and I'll be done when I am done I suppose.
<bot>: Girlfriend found out I was doing blow behind her back while she has depression and is consulting her therapist before she makes a decision to end it or not, what should I do?
