Need motivation from ladies who have lost weight all over (especially chest)!

I was overweight then after a year of hard work I lost a lot of weight and hit my weight goal. I wear small cloths now and small pants but also a small bra. My boyfriend of 2 years is happy for my weight loss but at the same time is sad because there's "nothing there" anymore. I'm debating whether or not to get implants. I've been feeling a bit depressed lately. I've even been exercising less this week. When my boyfriend and I watch a movie together he'll be pointing out when he spots a big chested woman. He'll compliment me too but I just feel worthless at the moment. Should I go for implants? I lost so much chest during weight loss.
