Whats wrong with my orchid?

[alinka]

Hey guys,
I really need your help!
I found an orchid next to my building. It was about 40 degrees outside and someone just left it there. I guess it was done blooming, so they just threw it out.
When i brought it home, it was dehydrated and had cold damage on its leaves. It was planted in very tight sphagnum moss, which was extremely soggy.
I repotted it in bark and put it over a tray pebble to give it some extra hydration. The roots were green and to my surprise, the root system was not that bad. Some rotten roots in the middle (which i cut off), but it has some roots growing out of the pot. Guess the orchid was trying to save itself.
First couple of days it was recovering and started to look better. The leaves started to plump up. However, after a few weeks the leaves started to yellow and there was no new leaf or root growth. It had lost almost all of its leaves. I checked the root system and the crown and it seems good to me, no crown or root rot.
The one baby leaf it had, has not grown at all.
I try not to water it much. Last couple of waterings i watered it with Superthrive with fertilizer, and dyna grow with fertilizer and still nothing.
I also wanted to mention that i don't keep it in a very lit location. Not sure if its needs much light since it barely has any leaves left.
If anyone can help me, and tell me what’s wrong or if this orchid is savable i would really appreciate it..
Also can an orchid survive with no leaves..

I'm attaching some pics first 5 pics were taken 3 days after I brought it home, next pics were taken yesterday when the plant lost almost all of its leaves..

You can also see the flower stalk that i cut off when i brought it home. It still didn't yellow or dry out..I don't know whats going on there..
