Medication question

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.

I have a question My OCD has felt almost invisible the past few weeks and now that is starting to stress me out a lot. Right now I am at a point in my treatement where I was asked if I would like to take medication. I told my therapist this week that I would like to try the medication based on how miserable I feel in during OCD flare ups. But now my brain always tells me that I only go throught this treatement etc. to seek attention and that I am just dramatic and should be ashamed of myself for wanting to take this medication. So now I am doubting if I should take the medication or not. Any advice?

These past few days I was fine. Minimal intrusive thoughts ,no anxiety etc(to add I'm on medication so maybe it's starting to work although it barely is 2 weeks) and today I got a sudden wave of anxiety and it started latching on some thoughts like" what if I'm in denial and I wanna break up with my bf? And what if erp doesn't work for me because I actually wanna break up with my bf?" But they didn't really stay long usually those thoughts would make me spiral for days or so, now they lasted for some hours. And now I'm trying to trigger myself into being anxious again because if I don't it means I don't have ocd and if I don't have ocd it means I don't love my bf and if I don't love my bf it means I have to break up. Idk if it makes sense but the lack of anxiety makes me wonder if I actually have ocd or not.
