38HH-I down to (hopefully) D or DD

My earliest memory of realising my breast were larger than. Penal was when I was 11 and was bullied in primary school for having to wear a bra. As you can imagine, it had been downhill from there.
I'm currently a 38HH and hating life with these massive mammaries. I am now 33yrs old and have decided now is the time for me. To do something for myself. I waited so long to do due to wanting to have a child an at least try breast feeding, and thankfully I was able to successfully breast for 9mths. Albeit, with great difficulty as I was always worried about smothering my poor little baby with my boobs. It's pretty hard breast feeding with large breasts.
But now, with my husbands inwaiverig support, we have pulled the trigger and are booked in for November 7th.....and
I can't. Fricken. Wait!!!!

Well [RS bleep]. We are all booked in. I say 'we' because me and 'the girls' equal more than 1 person, surely. Ha. So my PS assumes that he cold be removing anywhere from 1.5-2kgs from my chest. Sweet baby j, that's a lot of tissue. He's hoping to get my to a D-DD and I am fricken pumped. It's all hedging on one tiny problem though.
CHRONIC PERIDUCTAL MASTITIS ????
I have an absolutely gorgeous little blonde tornado that just turned 2 yesterday and 'no' I am not still breast feeding her and 'yes' I did stop breastfeeding her at 10mths old. So why is this still a problem, you ask? Well f*cked if I know. Your guess is as good as mine. I've been hospitalised twice. I have been on every single antibiotic you can think of. None worked. Its gone as far as abscessing twice. The first time I had an incision drainage (on my left areola) and that 1cm incision took 5mths to heal as there was still a pus collection forming and weeping out of the incision point. Finally it healed over and for 2 whole months I had no more pain, extreme nipple sensitivity (it was right under my nipple) I thought it had cleared up and I was stoked. Then just as I decided to make steps to get a breast reduction, it reared its ugly head again and abscessed and literally burst out of the incision site scar tissue the day before I went to consult with my PS for the first time. F*cking great. Quite disgusting too. However, that seems to have been a blessing in disguise as he was able to clean it out for me and hit the core of the cyst with some silver nitrate. The silver nitrate causes the cyst cavity to form into a small, solid lump. After two or three days the silver nitrate and cyst remains fall out on their own. It basically cauterises the site. He did all of this with no anaesthetic either. Frickin killed me. However, it seems it may have been worth every shiver that was sent down my spine as it's healed up in record time. Now obviously my surgery is dependant on it healing because if there is ANY pus/infection present at the time of surgery, obviously there's no way in hell he will operate. So fingers crossed for my final appointment with my PS on the 27th October. I hope he gives me the all clear!!
????????????????????

So I wear a 38HH, however, as you can see I get some spillage over the top of the cup. I imagine I’m somewhere in the realms of an ‘I’

There’s just no point going to get sized. Nowhere stocks my size and most bras I have bought online are somewhere in the vicinity of $100 and usually are a terrible fit and quite painful. So basically, I gave up.
