Got a surprise surgery date, feeling pretty overwhelmed

Today I got an email from my surgeon offering me a date for December of this year and I took it. I genuinely cannot express how excited I truly am but i think reality is setting in a bit and I’m starting to feel very overwhelmed. I truly didn’t expect to get a date anytime soon, I was honestly expecting to get surgery in like 3-4 years time and now it’s happening in only 2 months. And even tho I have been researching phallo since like 2019, right now I feel like I’m going in completely blind because i don’t know anything. Like what should I buy? What supplies do I need? What should I mention to my surgeon at our next appointment, how do i prepare my gf for my recovery at home? How do I prepare my home? What foods do I even buy? I feel so lost.

I feel like I need to prepare so much in so little time and all I have in my head is how I need new underwear even tho this is literally the least of my problems. I thought about asking for a different date but I do want this now, December of this year is literally the absolute best possible date I could have been given. I already have all of December and the first week of January off work as I had planned a trip abroad. This is perfect because I don’t have to go through the hassle of asking off for work or explaining anything about my surgery.

Idk I just need advice on how to confront these feelings and how to best prepare myself for this new phase of my life.
