As someone who easily gets anxious and stressed, I wonder how I could shove off the negative thoughts in my head. Once I met my other half, can they help me make the voices go away?
A loving companion acts simply by existing - as a companion. They can do their best not to make the thoughts and voices disappear, but rather quieten the effect. The unknowable future can be seen as knowable, with all its safety, thus help make life more bearable. They held options: it is always possible to leave town and start over, it is okay to live very moderately in a small place, it will be a good thing to just stay at home and have a domestic life. No one should expect them to be more either way: no feats any more, just being there is enough. They can't put more pressure to earn money, to impress others, or to act heroic. Surviving is what matters.
I'm imagining if I was at the rock bottom of life, an other half will assure they will stick around. Though it may not be it, again, they will be there to personally help make the future more manageable. When it gets terrible, we'll have each other's presence and that's enough. I'll lean on them and hold their spirits and that sounds pretty realistic.
Aside from being present, I hope the other half can instill the same fundamental message over and over again, "It will be OK." After all, even if OK isn't ideal, it's always what one always wants in the end. OK is better than abused, OK is better than death - it's always the better alternative in the mind that's suffering. Quite how the next year remains undeterminable yet, and more details have to be examined, but what is known is here and that's that we have each other. The future we see may be unendurable, but it won't need to be perfect for a huge basic reason: because there is love.
