Is this okay?

Peaches

So for the past year my weight has gone up and down and oh turned out that the main cause was the fact that i grew a couple inches. Now I’m about 5’3” and 120 lbs. I play basketball, so I’m currently in shape since the season started about a month ago, but I feel so self conscious about my weight because last year I was like 110 and just barely 5’. But I’ve been building up more muscle so I think that caused me to gain more weight. I’m just not sure, but felt a lot happier when I was 110 lbs. is it ok to be 120, and if I lose a little weight is that fine?
