hi, I'm not going to lie to you this is an extreme rescue case, but here is the verdict:
Prognosis: 50/50
She can technically bounce back, but she will remain puny. She suffered major stress (thirst, hunger, lack of light) which stopped her development.
Critical points
The stem: It is extremely thin and fragile (“stretchy”). It needs a stake or to be buried deeper when repotting.
Foliage: It only has its cotyledons and a few pairs of embryonic leaves. She has no energy reserves.
Direct action plan
Light: Give it a soft light not at full speed I would say 50% intensity if you are indoors.
Hydration: Gently moistens the substrate without drowning it (its roots are tiny).
Verdict: Give it a try for science, but don't expect a monster. She is in total “survival” mode.
I wish you courage and good success
