Best Decision, Best Surgeon.

Hello! I am 32 now and I had D boobs before I got to my senior school.
For a long time I hated them, I grew up in a hot country and could never wear bikinis or even swimsuits. I had stretch marks from the word go and they've never had much bounce to them! They are just a bit lifeless.
Surgery wasn't really ever an option. And I think I've thought up until now that I would regret getting it done. Despite having learnt how to dress them and learnt how to cover them I came out of a 'big boob' store over the summer in tears AGAIN because I was just SO uncomfortable.
If I ever had a massage of for some reason someone was touching my back or neck, they were shocked at how stiff and solid it was. It was so sore, and as I got a bit older I was just OVER them.
They don't suit my personality mainly. I'm very sporty and a bit of a tom boy, I dress pretty androgynous and don't wear make up or get my nails done etc.
I'm 5'10 and size 10 (UK)
My goal is this: I want the pain, clothes, underwear and swimwear problem gone, I don't want to just have a 'smaller problem'.
Does that make sense?! I therefore think I want to go down to a C.
Has anyone done this? GG-C? Did you regret going much smaller?
My instinct says I wont regret it but I wanted to see if anyone has experience. Also because I'm tall, I wonder if C wont be in proportion.
Any insight is welcomed!! I will upload some pics when I can.
Thanks!!

Adding some before pics as I didn’t have any of me out of clothes.
I am having my second consultation on Thursday 19th sept. All being well I will then go in for the surgery on 9th October. I’m excited. Psychologically I feel post surgery in that I have decided I’m getting it done and have sort of decided to ignore my boobs. I’ve stopped worrying and thinking so much about them. I’m wondering if I might be able to do yoga again? Maybe even complete my teacher training? Who knows. :)

I am 2 months post op, and I can safely say this is the best decision I have ever made. And choosing Dr Jallali to do the procedure is part of the reason I feel so good about it. He's a wizard! I am amazed at the shape he has achieved. I thought that you really sacrificed a bit with regards to shape - I don't know why I had that impression - but I have better looking boobs than I have EVER had. They are pert and round and just what I wanted.

I recommend Dr Jallali for his professionalism, experience and how concise he is. There's no messing around. He doesn't waste your time and he's very open about the different stages of the recovery, what to expect, how to look after the scarring and what might or might not happen. I had some specific extra questions before the surgery and we discussed each of them over the course of 2 consultations. I was able to be in touch with his PA Rachel if I had any concerns. She was lovely to deal with. The Welbeck hospital is located in the heart of Central London's most exclusive medical area..and the staff were all amazing after surgery. I can't thank or recommend Dr Jallali enough. 

By summer 2020 I'm sure my old boobs will feel a bit like a bad dream! :)
