To those in a relationship where you both have mental health problems... how the hell do you make it work?

Another one bites the dust for me, and I'm making the most of this time to try and process everything and work on myself now. But looking to the future... I see myself being forever alone.

This isn't so bad; I have a family and friends. But it feels like I'll never have anything meaningful again.

We both brought out the best in each other, but also the worst. And the worst aspects won out yet again.
