My cacti are getting worse! It seems like they are shriveling up from top to bottom. There is still some healthy looking cacti toward the base, but I'm not sure if they will survive. What do I do? Can I cut the top off?

I want to post on the cactus blog, but I don't have a subscription. Are there any members who don't mind posting for me just asking some cacti ppl to look at this blog...

Pls help if you can.
