Recently the last day or 2 I mentally and physically have been having some weird symptoms. It started yesterday night when I was about to sleep I had this weird half sleep half awake feeling, like if I could tell I was asleep but could wake up my body when I wanted to. For some reason I never felt like dozing off into sleep but felt like keeping my eyes closed and sitting there letting my body sleep. Whenever I would feel like forcing my body to wake up I would feel very weird and numb before eventually waking up fully. I don't know why this is but it's very worrying to me as it's not normal in anyway. I woke up the next day and have been feeling very out of body and numb all day, I never fully felt like I was myself the entire day and was worried in my head the entire time. I always have a anxiety thought that I might have a brain tumor or something because some of these things I feel are so hard to explain like this one, it's nearly 1 am and I keep going to this half asleep state and can feel like waking myself up at any moment. I don't know if this can be into play with these things but I also have been pretty inactive recently and haven't been using much energy so I don't know if that has to do with anything or not but I guess noting it helps. I feel very numb and out of body and feel like I will be able to force myself to wake up. Please help I don't know what's happening and my anxiety is constantly thinking I have a brain tumor or something outlandish like that.
Also I should note I don't take any meds for anxiety and depression
