Am I going insane or am I just stressed?

now dont take this offensively, but my opionion is you may be taking things out of proportion. everybody gossips- im sure you have to! but the best way to not be annoyed with them is just polietly confront them, say “im sorry, but I heard you talking aboutand I would appreciate it if you would stop gossiping, it really hurts to no people that do and im sure wouldnt like it either. So please if you cud hold back your gossip till I or any other is out of earshot, thank-you.” something like that. Dont worry I dont like epeople who gossip either! :) and as for the email…it may be jealousy. I dont think email someone needs to be done with permission. I no that you may feel angry bout this because you were “out of the loop” but next time ask him if he cud tell you when your emailing her. if he doesnt no her thou I wudnt worry. he is probly getting to no her better so the 3 of you can hangout or something. ! I hope my advice helped/funmail if you need any more !
