Tips for not being able to sleep because of racing thoughts?

My mind just starts racing with thoughts all day. I overthink aswell so I just tend to sit in the thoughts and can’t escape. I mostly have thoughts that tell me I don’t like the things I do like snowboarding or backpacking or if I even if I love my girlfriend. Deep down I know I do but then I start getting worried that the more I think these things the more they come true. Then I have tons and tons of more thoughts throughout the day and it just feels like I’m constantly having anxiety and constantly battling my brain over things that don’t even make sense. I’m only 17 and this is extremely hard and I feel like I’m wasting these teenage years. I don’t know what to do or where to go. I’ve picked up reading my bible and praying more but the thoughts persist please help.

What's a piece of advice you give when someone has constantly intrusive thoughts and ruminations that won't stop? Interested to see what you tell others.....more on this when I see some replies!!!

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?
