That's great that you're overall a healthy person (at least in your doctor's eyes). Funny because my doctors never recommended ways for me to gain weight, so I guess to them, they just accepted that I was small too. I really need to get a new doctor though, since I haven't seen one since after my son was born. I don't have a PCP right now, I mean. Also should probably get some of my moles checked out, which I probably need a referral to a dermatologist...
I'm sorry for your weight troubles though. I can understand not being happy with it, for sure. I had kind of the opposite experience in that of course I went up a size or two after I had my son, and I'm unable to go back down to what I was as far as size goes. It took me a good while to accept that fact, and some days I still get salty about it, but I'm proud to say that not once have I ever had an eating disorder or other unhealthy practices that would be a detriment to my health.
Goodbye, Voltra.
