How should I respond to these intrusive thoughts?

https://nocd.page.link/dbqYgS9T1qpwLYmg6 This link doesn't work for some. Let me know if it doesn't. Also the only person you should compare yourself is to who you were yesterday. We are all on our own individual and unique journeys. You're not living their life, you're living yours.

I have the exact same thoughts like "Girls won't accept me for my learning disabilities" and "There is something wrong with me". I have those thoughts all the time on top of contamination OCD, which is in itself is so isolating and lonely. I have been lonely for a relationship ever since I experienced a horrible break-up with my ex-girlfriend about 6 years ago. She accused me of saying all these things about her that I did not ever and would never say to anyone, let alone a girlfriend that I loved with my whole large heart. I got the best dog on the planet after that, and I love her to death, but I started isolating and sheltering myself in my parent's basement and not going out, especially since I had this year of huge growth with graduating college, buying my first car, and buying my first house. It took six years, still somewhat isolating, for me emotionally to find comfort, at least in part, by repeating over and over that it may not be my time to meet someone and while I say that, I'm open to figuring out why I am having those thoughts. Is it unfinished business from my past, or current unfinished business? I trust that when it is my time it will be my time, but I've also equally been pleasantly surprised by opportunities or "blessings in disguise" in the past, like when I met my ex-girlfriend at the time these thoughts really were at their peak. My only mistake was I wish I was more communicative about my obsessive thoughts with her and judged more carefully our future by how she responds. But, I've found myself over these six years open to the strange and mundane ways that opportunities to meet people happen. You never know how, when, or where you meet someone and where that may go. You also don't need to do what I do and isolate yourself. Take the moments to heal, but just be open to the mundane opportunities that come out of nowhere. You never know where they will lead.
