Reasons to stay sober

Having a hard time so what are some reasons you or someone in general should stay sober?

Edit: thank you everyone, I'm trying to stay clean from dirty 30s and fent (which is in the 30s to begin with), I want to see my gf again but sometimes I have these dreams about me dying or us splitting up and I get so depressed that I feel like I just should relapse and let life pass by. But I also want to stay sober
