OCD and relapse of drug abuse after too much alchohol

[OCD_0603]

Hi , i have been clean for 4 years now of drugs and have been diagnosed with OCD 2 years back . Have been in therapy ever since and have been doing very well till last weekend. Drinking was a part of my life but this particular night i got very very drunk and there were people around me who took drugs and i took as well as mi state of mind was blurred and my judgement clouded.
In return i have triggered the OCD full force again and i am struggling to cope with the whole relapse with the drugs thing. My therapist says that it is normal in the process of therapy for these things to happen, but due the OCD i have reocurrent thoughts that i might not be able to carry on and fall back into drug use. I know for a fact that if i was not drunk i would not have taken any drugs as i have not had desire to do so in a very long time. Everything in my life was going so well and now i am scared that i have blown it all away. I try to cope with the feeligns of guilt and forgive myself for what happened and still it haunts me. My best friend is supportive and my lover too, i have a good support system and i do not wish to ruin my life. Dealing with OCD is hard enough. Please give me some insight if possible as t how to help myself in this process.
thank you in advance !

another thing dude, if you have only used drugs and **** in 4 years ******* WHAT that amazing man if you dont keep doing it for weeks, that considered normal, man i know healthy people they drink like each weekend and live normal lives, if did what you just did, i would still be on a bender, i wouldnt have stopped at just that, so ******* good work for you, know what im saying, man even if you got off your face once every three months would be considered pretty healthy and normal. Relax, how are you doing anyway now?

i cant give you much advice about abuse, i just jumped off of methadone and i have OCD but what i have learned is to totally ignore my thoughts, i take em like you would bumping your elbow man. However the anxiety is what kills me, i never got it as thoughts dont worry me at all anymore, but my anxiety is ******* debilitating. Also i think  just maybe your being a little hard on your self, man your a human with feelings a heart a mind, give your self  a break if you can and have done it before spent years off of drugs you can do it again, so dont beat yourself up, lifes a journey and ours are all different.
You got love, guts and some ******* awesome wisdom, so what you took some drugs and alcohol, at least enjoy what fun you did have on em. You got everything kiddo, just lighten up on yourself eh?
