If there was one person you could go to and tell how you're feeling, even if it is trapped, and you would like some comfort, maybe going to your boyfriend could be a way for you two to become a little bit closer.

you don't have to pour everything out at once, but if you are going to, then prepare yourself for telling whatever and however much you feel like telling him. You aren't wrong for feeling scared, and don't ever feel scared to talk about it either. if you can share with your bf then don't be afraid to share with him how you are really feeling. Baby steps, everything in baby steps until your ready. You got this, don't give up on yourself <3
