You're never to old to do anything if you want it bad enough, as far as fitting in that's hard to say not knowing you or your personality. Any time you get a bunch of women together in an environment where how you look & how you perform is graded, it's all out cat fights
I noticed these days especially it's not too old to do anything. We all have different walks we go down and not everyone starts Hair school after high School. Even if they're Catty and unfriendly to work and train with you won't be working with them for forever. Don't let other people's problem deter you from following your dreams. there's rotten people everywhere and I am positive there are people much older in age who started beauty school much later then 34. your still young and you have to start and so you can go and get your foot in the door and start cutting peoples hair. don't let someone with a catty/sad attitude from allowing you to do what you wanna do. Do what you want, popular or not. It's not too late NoooooOOoo! Go!
