I have been where you are, with not one, but two gaping wounds where my nipples were.
This was caused by a double infection (so both sides) that had never been seen before by my surgeons. Very unlucky. They had to reopen the wounds around the nipples, rinse out all the bad stuff, and leave the wounds open so they could be flushed on a daily basis. It took 6 weeks to heal.
Needless to say I was also depressed. I never regretted surgery, but it sure was a hard road. I lost both my nipples in the process. Now, 4 years later, you can barely tell. It left no bad scars, and my nips are totoed on, and look real.
This too, shall pass.
