Is there a better place I should put this plant in my home? Why are the new shoots unraveling brown/brittle? And why are the leaves droopy and limp?
I believe I see some insects on it. Try spraying it with Neem Oil about once a week till it perks up. It needs bright but indirect light, so if it is getting full sun, move it to a southern or eastern exposure.
It also may be getting too much water. This article should help:

I’ve successfully water propagated a variety of my plants, especially Philodendrons and Pothos, but this particular Pothos continually rots during water propagation.
They should root easily in water or soil. Are you changing the water every couple of days? Bacteria builds up if the water is not changed.
Try just dipping the tips in rooting hormone and inserting in a container of moist potting soil (or half peat moss and half perlite). You can cover the pot and cutting with plastic to create a greenhouse effect.

Pothos plant has been doing that for couple of years.
They are usually easy-care plants, so it is probably an environmental or watering problem. Compare its care tips with how your plant fares:

How long does it typically take to propagate pothos? I have had mine In water for almost 3 weeks and see no growth of roots.
You should see some root development by 3 weeks. Did you remove the bottom leaf or two so at least one bare node is under water? The roots will come from the node. Replace the water about once a week. There also should be a couple leaves left above water. Keep the vase out of direct sun while propagating. Here is more:

Actually, my money plant is fine.. but the new leaves are growing so small and getting leggy.. and I don't have a moss stick as I have it on my window grill. So. What to do to get the news leaves grow normal and I don't want the leaves to be large like it gets on moss stick. And my old grown leaves are perfectly fine and big.. and also sometimes it have shot hole fungal disease is it the problem please tell
Unfortunately, your photos did not come through. If you used native soil, this is likely the issue. They will not tolerate compact, clay soils. This will cause them to be leggy and have small leaves.
Here is an article that will help you to care for the plant:

Very sudden onset of fuzzy, black spots. They're just on the top of the leaves. It's effecting the palm planted with it also. Both these plants are 25 years old. Probably need transplanting again. Just moved from dry Colorado to wet NC and this is new...
Likely, insects of nibbled on your leaves, and the sticky sap has gathered dust or mold!
I would spray them off with water, and use an insecticide/fungicide to prevent it in the future.

I have had the plant for several years and the base plant's leaves are healthy as in the growing end of the plant. It is the stems between where the leaves are turning yellow and falling off.
I am concerned about root rot. Check the roots for any mushy ones. Remove those if you find them and repot.
