Are you thinking of a duvet, maybe?

It does look like overwatering and potentially too little sunlight. My indoor Monsteras have grow lights for 12 hours, outdoor they do well under a patio with partial sun through the screens to give you an idea. They do well in heat and humidity, as long as the soil isn't crispy. Less of an issue indoors. Definitely let it dry out between waterings, best of luck!

Can we see the rest of the plant? What does the soil look like? How much sun is it getting? Was it transplanted recently? As others have said Monsteras do like to dry out. Water just the soil once every week or so when soil feels dry, every two in slower seasons. Do not spray the leaves, make sure when you water you are giving it enough to encourage deep roots.

I didn't think so either in my case, but my stomach lining didn't agree. I ended up doing a blood test through Everlywell and found out I'm allergic to a hell of a lot of things. I hope your issues clear up soon 💗

Something similar to this happened to me because of food allergies (undiagnosed wheat and milk casein, gastroenteritis for over a week). Can you try switching to plant based ensure?

Plants that get dramatic between waterings work well with self watering pots. I have my fittonia in them and there's a big difference between them and normal pots. I would suggest them for plants that don't like fully drying out between waterings.

I was hoping someone would bring up love languages! As someone who speaks gift giving and acts of service, when someone does something for me or gives me a truly thoughtful gift for me I adore it. On the other hand if I don't see those languages spoken, it makes me feel as though I'm not thought about as much as those I love and it can breed resentfulness.
