acceptance of thoughts, I don't know if what im doing is helping or feeding my ocd.

I recently got diagnosed with ocd and my first therapy session is in two days. I have checking compulsions and i guess i do the same with my pure-o, i analyse and revisit the past to find evidence to "check" and reassure myself that it's an irrational fear.

I was doing that last week non-stop and that and other school and life stress made me had a panic attack. I was doubting everything, it was hell. Im better now but still feel overly emotional.

I was reading on what to do about the obsessions which are what interfere with my life the most. How does one "accept" the thoughts? Lately instead of debating with the though i "tell it" that i already went over that (last week) and came to the conclusion that it was irrational. Sometimes the thoughts are questions, other statements. The statements i do my best to ignore to be whatever about them but it's hard because i feel if i don't correct them or debate them im accepting them as true.

Is this what im supposed to do? I know i'll get to talk to my psychiatrist and ask all these questions but i have work that i would like to get done and it would help if i knew what to do until then.

So sorry you are going through this.  You sound a lot like me.  What my mind has been able to come up with is astonishing, all the things I am able to what-if and catastrophize.  It is its own particular brand of hell.  

You are doing what you need to do which is practicing cognitive behavioral therapy.  Part of that is replacing the negative thought with a positive one which you are doing when you "tell it that I already went over that last week."  Sometimes it helps to write it down as well in a journal which you can then go back and look at as needed.  

The checking, well you have to stop yourself.  What I do is I say outloud  "the iron is off" when I turn it off so that when I have that moment of panic in the car on the way to work "did I turn the iron off?" I can fall back on the statement I said.  It works for everything in the house...the doors, the books in your backpack, etc.  The trick is that you CANNOT go back and look.  

You will benefit greatly from therapy.  They can teach you other ways as well such as proper breathing which helps with panic attacks.  If the psychiatrist does not teach CBT, then you may want to consider seeing a psychologist who specializes in this.  Conversely, you can find some CBT techniques on the web as well.

There is also the medication route which the psychiatrist can go over with you.  For myself, I use both CBT and medication.

I hope you feel better soon and keep me posted with your positive progress!
