Paranoia is Hindering Me from Enjoying this Reduction!

Hey guys, this is my first post on this sub, but I recently got a reduction 2 weeks ago! This sub has helped me a lot with the process! They are still swollen so I dont know what size they are not, but I used to be a 36G. The first week, I was so happy about my boobs like I just kept looking at them! Now, I am so paranoid that they are getting bigger again. I know this probably sounds really stupid and my friends and family tell me I am probably going through some type of dysmorphia in a sense. I am just so stressed that by boobs will grow again (i know sometimes they grow back after a while) so soon after surgery. I get so scared when I gain like 3 pounds because I feel like it went all to my boobs. Just wanted to rant! Would appreciate any insights!
