How do I get out of my head??

I can't focus on anything but my thoughts. I'm so inside my head, and my mom always tells me to focus on my body and my surroundings, but I can't, or maybe I just don't know how. I try to, but it doesn't help. The thoughts are still there :(

Hi - just for some context, I have OCD and ADHD. I hate bringing this up, but with these diagnoses, when intertwined, there is ALWAYS a thought. I never stop thinking. This is really hard, especially because I feel like I always need to be talking to someone. Whether it’s my friends or family, talking to people brings me down to earth from certain kinds of thought spirals. However, when I’m alone it is the hardest. When my friends don’t reply I have this compulsion to text again or I need to constantly check my notifications so that I have none left to check. But then to them or new people I talk to, this behavior probably comes across as overwhelming or too much. I’m trying to control it and use erp, but also, I have my moments where I’m just vunerable and give into the compulsion. It’s genuinely so embarassing and maybe not as big a deal as I’m making it out to be but, how do I manage? And how do I relax?

How to stop overthinking??
