I'm a struggling rural ptf, but I will be regular in 2 weeks. Should I quit?

I hate working here, and i suck at carrying. I'm not fast enough to finish routes when it's heavy. If it's light I am okay. But it still takes me a long time to finish a route.

I am really struggling rn, even after working here for a year. Should I just quit? I almost never am able to help after I finish a route, so that wouldn't be a reason for me to stay as a regular.

My office also really sucks and is super understaffed which I'm sure doesn't help (also management is mean)
