Ladies, advice...

So I’ve had this since my first was born, 6 years ago... my armpits are very huge and meaty, I never asked about it or asked a doctor.. because I’m embarrassed of it, my husband doesn’t know why he never sees me naked or in a tank top, because of this, I hide it from everyone, atleast I try, it sticks out a lot!!! It does decrease my mobility of the arms and does get painful during hot days because my sweat makes my arms squish this extra fat, well it’s getting worse after my third baby who mani had in October 2018, breast milk is coming out of them, they smell like mouldy milk, it hurts when my breast is full of milk also, and bras are making them uncomfortable.. I been so self conscious about my underarms for 6 years :( even when I lost weight after my second was born they were still there, idk what to do, I don’t even have money for surgery.. I just hate this, it’s ruining my self esteem and relationship :( help me... what should I do? I feel like a freak...
