Health anxiety is worsening after surgery; is medication my only option?

I’ve been struggling with OCD since middle school. Over the years I’ve had many different obsessions such as POCD, Harm OCD, and now Health Concern OCD. For the last 6 months my newest obsession has been thinking that I am having a heart attack. I constantly body check, google symptoms, ask others for reassurance. I live at my university which is a little bit far from home. This causes me to have to call my mom in the middle of the night every time I have a panic attack over this. My roommates a nursing major so she always offers to take my blood pressure which helps, but still I don’t enjoy living like this. I always feel bad bothering others, and constantly feel like a nuisance. If anyone else with these worries and obsessions can let me know new ways to cope with it that would be amazing:) I just started my switch from lexapro to prozac for my OCD and I’m hopefully starting ERP/CBT soon but any tips on how to help this would be amazing.

7 years ago I was a raging drug addict. I took any and all kinds of drugs without second thought of consequences. When I had my first child it’s like a switch flipped in my brain. Within her first 6 months of life I had over 12 visits to the ER. I was (still am) constantly afraid of developing a life threatening disease / illness or having a sudden health event (stroke / heart attack / heart failure / brain tumor / cancer ) develop. I’ve seen over 10 Specialist from autoimmune, heart, eyes, neurology , stomach , skin, etc. I’ve got a seemingly well bill of health but I become so hyper aware of every small change within my body. It’s. Constant state of fear and anxiety. Headache = likely tumor / aneurysm , small pain in chest or arm = heart problems , mild cold = covid or some rare disease , etc. Lately, my heart has been my fixation. I was having tachycardia going to the ER 2x a week. EKGs normal, 24hr monitor normal, X-RAY normal. Shortly after I notice my resting heart rate went down as low as 50bpm. I looked through my history over the months and that seems pretty normal for me I just hadn’t noticed before. Now I’ve been worried about my heart for weeks even tho my dr says I’m okay. It’s exhausting to be afraid of sickness and death 24/7. When I get focused on these thoughts it pulls me away from my kids and husband and daily tasks. I either full blown panic or shut down in fear. Anyone else relate? What helps you? I don’t want to rely on medications as I have so many adverse reactions to the 10+ I’ve tried! - oh year here’s another one - I’m afraid of allergic reactions as well I CONSTANTLY fear I will have an allergic reaction to medications / foods or over dose on things like Tylenol and Ibuprofen or mix meds and have reactions.

I feel like throughout my life my ocd has taken on different forms and I feel like every time I have issues it’s actually my ocd just getting bad again. Like someone reveals the scooby doo villain and surprise it’s just friggin ocd again . My main “flavor” that I have struggled with ever since the end of 2019 has been severe health ocd . So badly that I have had countless dr visits , hospital visits ranging from panic attacks to lingering anxiety that builds up after weeks of obsessing and loosing sleep . Is there anyone here with some tips to get through this kinda of thing? I’m in therapy and that has helped a lot but I still feel like I pops up and wrecks my life every 4 months or so
