To be honest, it helped me reveal my true self. I was feeling like I was going up to expectations of others, and not myself - like I couldn't reveal things about me I was scared to admit, because I felt alone. However, when I started liking MLP, I let go of all those thoughts (including my negative thoughts of the brony community) and started going towards how I feel about myself, making me feel happier and less depressed. I revealed things about myself (that I am bisexual, am agnostic and so on) and I felt comfortable with that knowing that there are people all around like that, and the brony fandom helped me realize that.
I guess what I'm saying is, it helped me be less afraid to show the true me, because despite what people think of you, there's many people out there who have similarities to you, like people who watch MLP!
