Hey Viv!
I was diagnosed last year at 31, and went through all the fertility stuff too (I don't have kids but want them!)
AND I had a MASSIVE needle phobia - HUGE, ever since I was a small child, girl you are going to kick that phobia so hard just out of immersion, believe you me.
I am so proud of you for doing it yourself! It's not a small thing, it's a huge thing. Buy yourself a trophy. <- Not sarcasm. When I finished my course I bought myself a charm for my bracelet so I could look at it and think damn, I did that. I'm amazing. I rocked in a corner and literally cried every time I had to do it, but am still amazing.
This treatment is your insurance policy, and it all sucks, all of it. It really really sucks. But when it comes to it you'll swallow that fear and do it. That's bravery: being scared and doing it anyway.
You can definitely do this, because in reality you're stronger and more resilient and simply more amazing than you ever imagined you were.
I'm pretty terrible with messages but if you want to chat/rant my inbox is always open.
