Delirious Help?

[Rheginn]

I'm a newer owner, I got a Mexican Red Knee sling in early February. It's molted 3 times while I've had it but I think this last one may have caused issues.

After letting it rest for a couple days I attempted to feed it. I started off with crickets but with Corvid I've been mealworms for the past few weeks. But it didn't want to eat so I took the worm back and let it alone for another 2 days.
Yesterday I noticed its legs trembling, it was very lethargic so I thought it had been dehydrated somehow and made sure that the substrate was extra saturated. I've heard mixed things about making an ICU since water=good but stress=bad so I tried to make its regular enclosure a similar environment. The end result was that after 8 or so hours it was much more responsive but couldn't seem to walk well. So I let it be overnight.
Today I found it not curled up but its legs were huddled close to its body and it is very lethargic again. In order to test its responsiveness I've been giving it small nudges, this time it raised its legs haphazardly, not in an attack pose but almost like it was drunk and trying to walk.

I'm not entirely sure what could be wrong since:
It has been kept in a more moist environment
There doesn't seem to be any damage to the carapace
It seemed to be fine directly after the molt

Any insight as to what has caused this and/or how I can help fix it would be much appreciated.

You haven't used any chemicals in your room have you?
You're right not to use an ICU as the stress off moving can do more harm than good as long as it has water close by. I wouldn't try to feed again for around a week.

Do you still have the last molt???

Sucking stomach

Everyone gets excited to have their spider finally molt and examine it for its sex. Theres one other thing you should be looking for and it's super easy to spot...the sucking stomach. I recently had a already sexed juvenile Tliltocatl Sabulosum molt so I just tossed her molt in the trash. A few...

Nope, no chemicals. I live in a smaller apartment so I keep it in my room since that's the warmest one I have.
When I tried to feed it last it didn't seem to have interest, I left the worm in there for about an hour and came back to it drowned in the water dish. I'm not entirely sure what I'm looking for but the molt doesn't seem to be much different from the last few.

After reading the post further, I looked at the molt more but between its size and brittleness I can't really say for sure.

I've put a few videos on my Google drive since the forum deosn't allow MP4. In each the tarantula is able to move but does so lazily and oddly. Its legs are splayed awkwardly and in the last one I give it a small nudge to show that it knows it's being prodded but isn't very responsive.

Sorry for the stressful situation.

You can rehydrate the molt with either Windex or water with a few drops of dish soap.
Let the molt soak overnight and you should be able to open it up and examine it.

Well the molt looks fine for the most part, at least as far as I can tell. The T has almost completely stopped moving and is settled inside the waterdish. I emptied it enough so it wouldn't accidentally drown itself but there's still a layer of water for it to rest in.
At this point I'm honestly surprised it's still trying to pull through but I guess there's nothing I can do but wait and see.
