Phal yellowing wrinkly leaves, only a few small roots left

[jackpot]

Hi everyone!

I would like some help with a phal that turned into a rescue project. I got it before I knew how to properly care for phalaenopsis orchids a bit. So far, it's only going downhill with this one, and I don't know what to do anymore.

A lot of the roots got rotted, there are still a couple of roots left with green tips however. Now all the roots that are left, are so small I can't even pot it in a way that would make it stable, they don't really go past the tip of the base on the bottom.
The leaves are so wrinkly and weak, but I don't know how to properly water or how to keep it it at this point. I prefer to have them in plastic pots.

Now last month most of my orchids started putting out flower spikes, this is also when this one started something that looks like a spike. It's the little growth on the right of the picture. But now I noticed something is also starting to grow on the left side. I don't think it's doing that because it's happy. Whatever it is, I would like to get this orchis back to health but I don't know how. Any suggestions?

Right now I just mist the roots every day, and then place it kind of on top of the bark it used to sit in. A few days ago, one of the leaves started to yellow. It's dying, how can I keep it more moist?
