Does hyrimoz really make you as immune compromised as a chemo patient? Have contamination OCD already, not excited for this journey

Starting hyrimoz next week and I am TERRIFIED. There’s a 100% chance my body will get more disabled if I don’t I know that which is why I’m going to take it. Today on the phone with the pharmacist I let them know I’m afraid of getting sick all the time and how severe it could be, I asked “compare to a chemo patient, how serious do I need to be about things” and they said “like a chemo patient would”. For someone who already has contamination OCD (been in therapy for years) this is scaring the hell out of me. Any words of advice? Anyone else with contamination ocd on a biologic who can help me navigate this? Thanks all!
