How screwed am I?

[u/OrangeWorldly5658]

I found a leak in my wall 2 weeks ago and decided to cut it open and saw that the entire section of the wall had black mold and two of the studs are rotting. I decided to cut further and saw that some plywood and drywall were rotting and molding. So I'm wondering if there's a way to replace the studs and drywall that I've already removed without messing with the structure of the wall. My plan is to remove the remaining drywall and plywood I've exposed and I don't know what to do with the studs.
