about two days w/o reassurance!!

I'm struggling. Not going to seek the reassurance I feel I NEED.

So I've been working to address my OCD for about a month now. So far, I haven't been working on it with a therapist and have instead been trying to create my own exposure exercises. The primary obsession I'm working on is the fear that I'm somehow flawed or invalid on a fundamental level. The best way I can describe it it is that its similar to the feeling you get when you have germ OCD and you feel contaminated, except my whole existence and being feels contaminated, so to speak. I've identified a list of triggers, and a list of compulsions (pretty much all mental) that I've noticed myself performing. I started out by doing imaginal exposures and scripts where I'd write out triggering fictional scenarios and read them over and over, combined with mindfulness techniques to focus on my breath and bring myself back to the present when I noticed myself performing compulsions mentally. At first it worked to some extent, but eventually I started to feel like the stories I was writing about this obsession weren't triggering any anxiety anymore or a very low level. So I stopped reading them and focused solely on improving my ability to stay present and identifying compulsions as I perform them, and disengaging. Now, I'm at the point where it seems like my general anxiety levels throughout the day are lower, and the triggers I've identified are producing noticeably less anxiety. But that makes me wonder if somehow I'm just secretly doing mental compulsions without knowing it? Is only a month of rather disorganized and unstructured ERP enough to produce this much improvement? To avoid giving me re-assurance, I'd appreciate if you guys don't directly answer those questions, maybe just provide some possibilities or your own experiences so I can get a better idea of where I'm at. Any info would be appreciated. Thanks!

So a few months ago a suffered with a really bad panic attack (I didn’t know what it was at the time) and my anxiety has never been the same since. It’s almost like I had to relearn living life with this new anxiety. I have had to force myself into uncomfy situations to remind myself that this will not over come me. It seems that my anxiety stems from being in a place I’m not familiar with or have this feeling that I may be stuck and can’t get out back to a place where my body feels at ease. I wanted to expose myself to a very uncomfortable situation to prove that I will be ok. So I took myself and 15 year old brother on a 3 day long trip to 2 major cities NYC and Philly. I did have some small moments where I felt heart palpitations or that I couldn’t relax (mainly driving into these cities/ being stuck in traffic is what spiked it) But over all I’m feeling really happy with how I managed the trip. I think I’m just mourning the person I was before this anxiety. A few years ago I would’ve never felt that kind of anxiety on the trip. Maybe leading up to it. But I’m hoping the more I continue to force myself out of this bubble that anxiety wants to put me in, I will begin to regain the ability to be away from home and relax again.
