I think that what you feel is perfectly normal! and from your avatar, you look awesome
I can relate to your feelings for sure. I've lost the weight to get down to 170 before so am finding that the 20 lbs to make it back down feel more tedious than they are exciting. I've done it before, I feel I should be able to do it again. Will I feel like celebrating once I get back to 170? maybe... but I more than likely will just feel content. Even before, I felt like I did great but suddenly my body image wasn't as much of a priority as it had been before. I felt comfortable in my skin. I was able to find clothes that fit me well easily. It didn't occur to me that I should be celebrating anything so I guess that's why I didn't really feel let down by it. After losing 45 lbs, I felt normal. And I was happy with that.
Lots of things happen as we adjust to our new selves. And if you're not as excited about the weightloss itself, maybe that's your mind's way of accepting all that you have accomplished and looking forward to the next stage of life.
Oh, and it may also be because the changes probably haven't been so obvious as they used to be for you? I personally fit into the same things I fit into when I was 170. They're definately tighter and that's one of the reasons why I am re-focusing on getting my weight down again -- but it's not an obvious difference.
And one more thing... I'm not a fan of regular exercise. It's very hard to fit into my schedule. But i know for a fact that when I do regular muscle training and activity every day, THAT is when I feel the best. So ultimately, if I were in your shoes (which I have been), I would reflect on everything else in my life to identify what I can improve on and find happiness in.
I happened to meet my husband when I was 170 lbs. He was the person that made me feel especially good about how I looked and is a constant energy and ego boost 5 years later.
Wow, this was far longer than I had intended. Guess I'm just looking forward to being where you are and counting on it being equally as uneventful.
