Just need to vent to fellow OCD members. Wife and I just bought a house we instant fell in love with the first time we saw it. The house is nice but a big shift from living in our condo and a totally different neighborhood(OCD Trigger 1). On top of that we had evidence of mice (OCD Trigger 2).
I just wish I could stop obsessing so much. The rational me says everything’s going to be ok but my OCD won’t let it go. I’m so exhausted living like this
Hi fuzzymode- I can relate to you especially re the mice. I have OCD as well and two years ago I discovered mice droppings in some of our Christmas decorations that were in cardboard boxes in the basement. That freaked me out and I had to throw away some treasured items because I was worried about contamination to others. I was able to salvage some of my most treasured by wiping down with Lysol wipes, etc. I had to just convince myself that people deal with this all the time and the anxiety got better.
It's certainly difficult to leave one property and move into another. I am going to have to move to a smaller place and I keep putting it off!
It involves breaking emotional ties that you've built up with your old place and, in your case, getting to grips with a new neighbourhood. It often takes some getting used to.
Don't try to rationalize it too much. That is just overthinking. It sounds as though you've made a good choice, now give yourself enough space to learn to enjoy it and fall in love with it all over again.
As for the unwanted guests, I sympathize! I've had them as well! I don't mind spiders and other creepy crawlies, but rodents I find just disgusting!
I've managed to discourage them by making sure that anything edible is kept out of their way. Also make sure any holes they can get in are stopped up. I'm told that they can get in a gap the diameter of a pencil! If they persist in availing themselves of your hospitality, pest controllers might be the answer.
