VERY FRUSTRATED after bf fight.

My boyfriend and I got into a large talk that really left me so frustrated. He has some personal issues that he doesn't tell to anyone including me since that is apart of his personality. Which i understand. The conversation just got really frustrating to me because I just want everything to be okay but I understand I need to fix the issues in our relationship. I'm so upset and idk how to handle my emotions. I can't talk to anyone about it. I need advice.
