Scared to take meds for my anxiety

My dr prescribed me meds for my anxiety (sertraline) and ofcourse I’m too anxious to even take it. I’m scared because I read online it can cause “serotonin syndrome” 🤦🏻‍♀️ ugh. I know I just need to take it but my anxiety is making it hard. Does anyone else have anxiety and panic over this? Please no hate I know it sounds ridiculous but it’s a real fear to me 😕 I’m starting therapy soon too
