Does exercising/ eating healthy help ocd & anxiety?

It started when I became an adult, and started receiving my mental health diagnosis. I hyper fixated on each and every action I did and how it could be related to my diagnosis’s. It then lead to fixation to my physical health — making appointments and seeing every specialist I can to rule out every possibility. I currently have been suffering with obstructive sleep. I woke up the past few days with severe pain from the lack of sleep whilst believing I was oversleeping. Luckily my fit watch tracks my sleep cycle and it turns out I am not receiving any sleep. I had an extreme panic attack — bursting into tears on the phone with my mom wondering what this case might be. She told me it could be sleep apnea and that a simple sleep study could figure this out. However, knowing my family history I made appointments to every specialist I can to make sure it is nothing serious. The unknown of health can be scary to me. Watching my mother suffer with her physical health chronically since I was a child lead me to be very conscious and aware of how my body is functioning. This morning was one of the worst moments of physical pain. I should just take one step at a time with the sleep doctor instead of taking measures to see every specialist that could pertain with this issue. However, that is very hard to me. I don’t want to ever wake up in the pain I was this morning. Does anyone else suffer with health-related OCD? And if so, how do you find a sense of ease during moments like I expressed?

Does anyone have any experience with this? I wake up early with severe, severe anxiety and nothing seems to help. I try embracing the anxiety, breathing, and exercising. But these things only seem to help a little. Fortunately, I do think the length of the attacks are getting shorter (mainly because I'm still trying my best to live normally in spite of them), but they are still lasting a good 5-6 hours. They are quite debilitating. Does anyone have any advice for dealing with these? I've read much about potential solutions (being okay with the anxiety), but I was looking for some personal antecdotes. Thank you

I just got diagnosed with ocd and she suggested I think about taking lexapro for it. Has anybody tried that and does it help at all?
