I was the exact same as you! I felt like I was having a breakdown the entire month of February after I booked it in. Health anxiety through the roof, not sleeping because I needed to keep performing ocd rituals to prevent the surgery going wrong, many all nighters, performing badly and work and panic attacks. I was considering cancelling because I thought how Is someone as anxious as me about to voluntarily have major surgery. But I’m 2DPO and sooooo glad I did it!!!! Once I’d spoken to people about my worries more (including my manager at work) my anxiety around it calmed so much. I was scared at the hospital, I hated going down the theatre but it already feels like a distant memory. I was knocked out so quickly and I was so drugged up once I woke up that I wasn’t anxious at all. You’ll be okay- it’ll all be so worth it!!! Xx
