I think what you are experiencing is perfectly normal given what has happened . As others have pointed out March wasn't long ago and you were just sitting in survival mode at that time and praying you would heal. Well thankfully you have. Physically. But mentally you have only just begun to acknowledge your loss if your breasts never mind your current disfigurement.
I agree that looking at a new appointment to discuss your options is paramount. Your last surgeries were not around asthetics but just ridding the necrosed area. Just wondering why they removed the implant...was there not enough skin coverage at the time? Has enough time gone by where a tissue expander be considered and start the process again, given your remaining skin now has adequate blood supply? These are all appropriate questions. A nipple tattoo can be considered much later once that part is sorted if they have concerns of creating a new nipple.
A counsellor may also be helpful but I think currently you need to really know "Is this it?..or can things be looked at again or the future? ". After that discussion you can begin to process things and accept what you can. Kath x
