The fact is, the economic climate right now sucks...it sucks big time!
I would never discourage anyone from chasing their dreams, go for it! go for it at full speed! what I will say is, dont be scared of taking the long path to reaching your goal. maybe to earn enough money you have to work as a care assistant instead, helping to feed or bath those that can no longer take care of themselves - this shows dedication to the job.
If you put your mind to it, you will succeed, as scary as it is have faith in yourself
also yes, there will always be demand
