Many people who have battled weight for a long time don't recognize themselves in the mirror after they've lost a significant amount of weight.
Others of us are the opposite: For those who haven't battled weight for a long time, when we gain a lot of weight, we don't recognize ourselves anymore. That's one motivator for pursuing surgery! Then, when we do lose a lot of weight, we start recognizing ourselves in the mirror again.
No matter which group you fall into, you are not alone.
Good luck.
