what should I do?

We are both struggling and hurting but neither one is causing it.. Both wish to relieve the other of their pains.. still what we keep doing is hurting each other again and again and again.. Both feel responsible.. Both feel unhappy.. & neither (as per my understanding) seems to be able to get out this gloomy state of mind.. It's only in the beginning the first 6 mnths.. when everything was alright.. ever since the same things keep happening over and over again.. no we are not in a relationship.. never were.. but the connection was like that between Husband and a Wife.. I have no idea where it's going.. but i just wish to put an end to her problems asap.. but idk how.. I feel tired of my own self.. top it off with the fact that i too have serious physical and mental health issues combined with recently arose social problems too.. I m always under scrutiny for my smallest actions.. And for her even the smallest of my actions matter.. the smallest of my mistakes affect her a lott.. We stay in different cities.. Can hardly meet.. Social media is the only form of interaction currently.. She loses her patience very often.. she'd call me bro to tease me or whatever reason once a month or similar.. but that affects my decision making a lot ..
