No, it doesn't look like a lost cause.....you aren't feeding it anything are you? The reason I ask is because you said the leaves are getting darker. and you said the leaves feel dry...Don't water so much, try to water when the pot is very light and then give it a GOOD drink, not just a little.... then wait patiently to dry out again...if you have higher temps you may need to water more often.... remember to not feed it just yet....Here are some pics of a plant that I abused terribly but kept at it (it's the one in the white container in the second pic).....Good Luck! B It may need to be repotted, that will cause droop too.
