Have you talked to someone about the practicalities?
My sister had small tubular breasts. She wouldn't have been eligible for surgery on the NHS so took a private payment plan. The surgeon was lovely but as she had so little breast tissue, the finished result was not good... she was warned, but the skin looked very stretched and sore, and she had them removed 8 months later. I know that isn't what you'll want to hear, but I wish someone had told her. She's got surgery scars now, which don't help how she feels about herself. She probably wouldn't have listened, but she'd have been a bit prepared, at least.
I don't think changing location will help with surgery, unless you change your address. Then there may be a minimum time, and you'd need to go through the referral process again.
I am sorry that you're struggling with this ❤️
I think it probably is worth engaging with mental health services too, as the physical surgery doesn't always do everything you think it will. For my sister, she thought having boobs would help, but she found it made her feel strange - that they weren't "her", and she was now pretending. She was devastated.
She's also now got a higher risk of lymphoma, even though she didn't have them for very long.
