Reddit mentions of Getting Over OCD, Second Edition: A 10-Step Workbook for Taking Back Your Life (The Guilford Self-Help Workbook Series)

This is an obsession. Uncertainty is part of life and most people accept this. Right now, your OCD is preventing your brain from properly assessing the likelihood (or rather unlikelihood) of devastating events actually occurring. Your OCD is preventing you from living with the uncertainty and this is something a lot of us sufferers struggle with.

As with all obsessions, the rule is to not engage with them in a compulsive way.

Compulsions include:

• consciously thinking about your obsessions (unless you are doing this for exposure therapy)
  
  
• mentally over analyzing your obsessions
  
  
• researching your obsessions (unless the research is for therapy purposes)
  
  
• seeking reassurance
  
  
• and any action whether mental, physical, or avoidant that you do to alleviate discomfort caused by obsessions
  
  The key here is to combat the OCD, not the obsessions. When an obsessive thought comes into your mind, you can let it just float by. Do not consciously think about it, but do not attempt to push it out of your mind either. If you let it be, it will go away.
  
  There are other therapy techniques as well. And it helps to have a plan so you can slowly wean yourself off of your compulsions. Going cold turky can be extremely difficult. I suggest seeing a therapist who is knowledgeable about OCD. You can also get an OCD workbook. I used this one and found it helpful: Getting Over OCD by Jonathan Abramowitz
  
  If you cannot afford the book, you can still print the worksheets in the book for free at https://www.guilford.com/abramowitz-forms
  
  And of course there are a lot of online sources you can use to help you understand OCD and fill out those worksheets.
  
  Edit:
  
  I looked through your post history and would like to add a couple of things.
  
  Your brain is always active and it will always be churning out nonsense. Everyone's brain does this. Everyone has disturbing, unwanted, intrusive thoughts. A healthy brain is able to filter out these intrusive thoughts, but an OCD brain latches onto them, creating an obsession.
  
  This is why I mentioned that you must combat the OCD itself, not the obsession. Obsessions can change and be replaced by new ones. Almost any attempt to logic away an obsession is a compulsion. Besides, you cannot logic away the illogical. But when you really understand OCD, how it works, and how to treat it, you will have the tools to deal with whatever OCD tries to throw at you.

Yes, contamination/perfectionism for a long time.

I've been let go by my most recent psychologists because they say I'm wasting my money with them as I won't do the exposures. They can't follow me home and keep me accountable. The best thing I've found is to tell myself "this is unnecessary" and walk away from whatever it is that I am checking or feel uncomfortable about. Then wallow in it. Don't distract self with the phone or a book let myself be uncomfortable. This is easier said than done. Inpatient places are 25k and up they keep giving that to me as an option. That or "deep brain stimulation."

Quotes seem to help. Simple one-liners that put things into perspective. "Do you want to be miserable temporarily and fight the obsession or miserable indefinitely with the guarantee of ongoing obsessions controlling you" that kind of thing. Put post-it notes of that stuff everywhere. OCD=Control+Irrational.

Contamination/perfectionism has led to procrastination or avoidance of tasks altogether that have had major impacts. I ruminate about past mistakes, have not learned the art of letting go in that regard or in regard to simple daily routines.

The Abramowitz book seems to be the go-to for what to follow when doing the ERP with therapists. Plan is to use that to attack it in a structured manner. I seem to be able to resist some things and then let other things through. Previous therapists gave specific assignments and wanted those completed before moving on so maybe my attempt to "remove the band-aid" all at once is a bad idea. Want to try the NOCD app, I haven't messed around with that much. The thing is I have these books, apps, and resources and don't take action with them. It comes down to being po'ed at the OCD enough to say alright do I want to be comfortable for 15 minutes by succumbing to this obsession and thus guarantee ongoing misery or move on and get out of these routines and disrupters of joy?

I must be still comfortable enough with the OCD that I am unwilling to take control from it. I've been at wit's end plenty times and asked myself the question that indicates either the start of great change in life or the start of depression. "Am I going to live my life like this?"
