Her and I both have bad days, and she relies on me solely for support with her mental health to the point that it took me months to even convince her to see a therapist, with whom her first appointment is this coming Thursday. Most of the time, it's difficult, but I manage because I love her and through trial and error, I've found some things that seem help some. But when we're both having a bad day, her issues become too much for me to handle and I end up having to shut her out in order to save myself. What can I do to help her without drowning myself?
