gain 10 pounds

I hate when people complain about me being soo skinny. While it might difficult for them to lose 10 pounds, it’s equally hard for me to gain it. :/
I’m 5’6-7” and I weigh usually between 105 and 110. It’s amazing how often my weight changes throughout any given day, but it never seems to go above 110 no matter what.
I’m nowhere near comfortable being this skinny. I feel fragile, I don’t find being this skinny attractive, and I know it’s unhealthy.
