High Anxiety | Need to Sleep | Please Help

Hi everyone! I’m not sure if anyone has had any issues with sleep and anxiety but these past couple of weeks I’ve been suffering with anxiety when trying to sleep. My mind will latch on to the idea that I won’t sleep and I’ll continuously try to fall asleep and end up psychoanalyzing everything im doing . Usually I end up freaking out and not sleeping and waking up with maybe >2 hrs a sleep a night and have an awful day the next day. I’m lowkey hopeless in this situation, I’ve tried melatonin, sleeping early, limited screen time and nothing will work.. does anyone have any tips and tricks on what to do?

My mind keeps telling me “something is wrong with you. the weird feeling you are feeling or the weird tingling you are feeling or there is a weird mark on your body. Those are actually a severe symptom and by ignoring it you could die!” Or especially the constant, “go to the emergency room because this impending doom you are feeling, yeah that’s because your gonna die shortly” It doesn’t help whenever people say “well if something was wrong your body would tell you” because my mind keeps telling me that what I’m feeling is proof something is wrong and I need to get it checked out. That I actually am severely sick and that I need to get it checked out as soon as possible, that if I get one more test than I’ll be okay because it will prove nothing is wrong. How do I tell my mind that it’s just anxiety whenever my mind keeps telling me “well if you keep saying that you could be ignoring something more serious.” Or “the doctors are just brushing you off..something is wrong with you” It’s hard to live with my thoughts whenever they are constantly coming up with ways to challenge me and challenge logic. New reasons on why I need to get this checked out because “I’m just being ignored” or “no one is listening to me so I’ll just end up dying” My symptoms range from weak and shaking legs and body to dizzy and unbalanced and dissociated. Recently I’ve been getting this tingling feeling inside my head and on the back of my neck. And my temples have pressure on them. My body keeps coming up with new symptoms I need to worry about, whenever most of them are probably caused by severe and constant anxiety. So severe I can’t even leave the house because I constantly worry about whether this is severe and something will happen if I leave the house. I need immediate ways to start fixing this because it’s especially horrible whenever my period comes around and my anxiety/depression is already higher than usual. I’ve even started considering taking medication (Zoloft, 25mg) which is another trigger for me, I worry about the symptoms I might get from taking it. That’s how you know it’s gotten pretty bad whenever I’ve come to taking something that I’ve been actively avoiding. What are your thoughts? Do I take the medication? What are ways I can deal with my symptoms that seem so severe in the moment but pass by once I’m not anxious? What are ways my thoughts can ease and I stop taking every symptom as something serious, because at the end of the day my anxiety is most likely the reason I have these horrible symptoms. I’ve always been extremely healthy and everytime I go to the doctors they express how healthy I am with all the tests I’ve had.

Does anyone have tips on good sleep hygeine? What does everyone use to relax and wind down before bedtime?
