Insecurities :(

So yesterday I decided I was going to do some makeup and it’s was for Fourth of July, so i was really feeling it and all so I post on this other app that’s all for makeup, thinking yeah they’re gonna hype me up and give me tips on how to do better makeup right? No no no no. I posted a few pics and then one person, just one comments and says “well if you didn’t have such a big head then you’d be cute” she then went on to say I wasn’t that good and all. So yeah, since then I’ve been feeling horrible about how I look and I just wanna hide..
