How Can Breast Size Be Augmented?

i am really down and have been for years about the size of my breasts i have been to the gp but im to embarressed to tell them exactly how i feel. i am even thinking about doing my own surgery with chicken fillets. my doctor told me to get in contact with spire hospital but the cost is too much and now im feeling more down knowing that i will never take my daughter swimming or get in the bath with her, that i will never wear nice clothes. me and my partner are engaged but i dont want to wear a wedding dress due to this problem it is really affecting my life and i hate it but cant do anything about it but insert my own fillets.
