please help! newbie here
My plant is dying and I don't know what to do! I have this Massangeana plant (I think) and it started dying all of a sudden. I know this may sound stupid but I am pretty attached to this plant, it's the first plant that I have owned, and I got it when I first got my own place, and at the same time I also got my first puppy and started grad school, so I group all of those together and I really want to save this plant. It used to very healthy, I kept it in the garage for the winter it was doing just fine and I noticed one day that it started to look like it was wilting, so I put some water in it and thought that it will be OK, but it started to get worse in the next few days. So I thought that I might be too cold and I brought it inside and put it in a place with not much sunlight. The next day it looked way worse, I thought maybe it was adjusting and it will get better, and the next day (today) it looked like it has died. I just don't understand how it looked from looking kind sad to dead in three days. It's not overwatered. I moved it into a pot twice as big about 8 months ago, the pot has drainage holes that I drilled. I don't know what to do, I just gave it a bath thinking that it might help but I really have no experience and would love some advice. I am not sure if it can be saved but I would like to try. Thank you to much!
