Need advice - Thoughts

Hi everyone,

I was diagnosed with OCD 6 years ago and I had therapy and took medication for about 2 years. Then I gradually stopped taking the meds (after the approval of my therapist and on her watch) and I was doing great. My OCD was pretty much always the fear of contaminating things I care for and value. If I was getting a winter jacket, I had to be mentally clean to not make it dirty. And by mentally clean I mean I couldn't wear that jacket when my brain was thinking of something I didn't want it to think of (like a bad memory) because if i did I felt like that jacket was ruined or contaminated through a bad memory and that I would always associate that jacket with it, which made my life a living hell years ago. I couldn't even buy books let alone an expensive commitment like a phone or signing up for a club or something like that because my brain would always ruin my best moments by reminding me of terrible memories or thoughts (you all know having OCD is like having an enemy in your head, it does its best to annoy you and do the opposite of what you want it to do) Lately I feel like this fear of contaminating important things is coming back because in the coming weeks I will have to register, make contracts, move houses, buy new things, etc, which is making me extremely nervous. My brain has started to remind me of bad memories and ruin my good moments lately and I don't want the coming weeks to be hell because like I said I will have a lot of paperwork and big shopping to do. I currently can't go to therapy because I'm abroad and also it's not extremely bad yet. I'm just looking for some tips and tricks to fight back before I fall into the loop again like years ago. What should I do to stop my brain from reminding me of bad memories/thoughts and to not feel like I'm contaminating things with my bad memories/thoughts?

Thank you all in advance.
