How can I stop being so sensitive?

So I’m a really sensitive person. Pretty much anything will hurt my feelings. I get kinda upset when people disagree with me… For example, sometimes my friends will insult the things I like or what I believe in. Even if they just hint at disagreeing with the things I like or believe in, it offends me and often ends up ruining my day.

Two examples I can think of right now is when one of my friends insulted my favorite show, saying she can’t wait until it ends and that it’s so annoying and the people who like it are annoying too. She apologized later for saying that, but it still kind of bugs me, because when I go on her deviantART profile I see a bunch of things saying how much she hates the show and the fans. It’s her profile and I know she can do what she wants with it but it kind of hurts my feelings.

Also, another one of my friends acts really annoyed whenever a theist brings up their religion even when they’re not forcing it onto her. She’s atheist, and one time we were at a bookstore and an author was there and she survived breast cancer. The author was saying how she’s so thankful to God that He saved her life and stuff. When the author said that, my friend looked at me and rolled her eyes as if she was really annoyed. I’m a theist and this was a little hurtful. I respect the fact that my friend is atheist, she doesn’t have to agree with what theists say but it annoyed me how she was irritated that a lady was appreciative to her God that she survived when it didn’t affect my friend at all.

I don’t know, sometimes my friends and family just insult what I like and what I believe in. I think a lot of the times they do this subconsciously, and I know they don’t mean to hurt me, but it hurts my feelings a lot anyway and ends up ruining my day and making me feel really bad about myself. Is there a way I can be less sensitive? It really makes me sad and I don’t want to be this sensitive anymore. Thanks for your help!
