after pregnancy and feeding?

Before pregnancy my were a 38D during pregnancy they went up to a 38DD. I fed for 5 weeks but because of a medication i had to start taking(i have psoriasis that came back and it was getting severe)i had to stop feeding. my son is 11 weeks old now and my are saggy now... please dont be rude but its depressing me horribly! its not like theyre horribly saggy or anything but they arent perky like before, anyone went through this? can i do or take anything that will make them firmer or perkier again? i know they will never be the same again but if i could get them any better at all i would be happy. please moms give advice or anything helpful.
