Hello Keely,
I have the same experience with my family. Most of them are really not trying to adjust and refuse to use correct pronouns. One of my sisters called me "she" the other day which was really nice, but that's really it. I'm still treated the same way for the most part which has it's pros and cons. To be honest, I'm not really expecting our relationship to change other than their acceptance. At the end of the day, I am the same person.
As for my friends, they are really accepting and have always used the right pronouns (even before my transition). Besides, I don't think I could really shock people by doing things non-masculine. I'm still the same person in terms of my behavior except being a little less guarded and self conscious. People that weren't okay with who I am stopped being friends with me a long time ago. No point in being friends with someone if the don't accept you.
I'm really sorry you are having a hard time with this. I wish people would be more understanding in this world. However, is it possible that your friends are just kidding around? Maybe they have good intentions despite the fact that they are hurting you. If you're not sure, maybe talking with them will help. As for family, how is it that they are treating you? I understand you want the correct pronouns to be used, but what else are they doing that hurts? You are totally justified in these feelings (I'll never foget how I felt when I first came out) but keep in mind that these things take time. People need to adjust.
Only you can decide whats right for you. Like others said, going back in the closet would be a poor choice for some of us, but you know yourself best. If you think the transgender life is harder than you can handle or it turns out you're not interested in going through everything, that's you decision. I'll simply say that I myself have found some of the sacrifices and hardships worth it at times despite the fact that I too wanted to go back in the closet and just make all the pain and difficulties stop. The question you have to ask is how mch is this all worth to you. Think about it. There is no shame doing some introspection to ensure you make the right choice.
Anyway, I really hope everything goes well no matter what you do. Good luck.
