Yeah so I panicked and messaged him. I decided to keep being honest, I told him I was paranoid he would try and hospitalize me for telling him about those thoughts, AND that I was scared to go to session tomorrow. I asked him to promise me that nothing was going to happen if I went tomorow, and he immidiatly replied..."promise".
I guess it's all good, I don't think he would make a promise to me he would break.
