I'm sorry.

I can't advise you. I can't make it better. I wish I could.

I can tell you this: don't let the labels scare you. I have nine diagnoses. (MDD, PTSD, GAD, social anxiety, specific phobia, Asperger's, conversion, OCD, and I am bordering on psychotic)
Often they go hand in hand. For example your OCD is probably heavily influenced by your PTSD and your bipolar 'cycles'. Treating one will likely help the others.

Are you seeing a therapist?
