You can do whatever you want. If you want to be a ho who works at a brothel, or on the streets (assuming you are a female) then I think you would be great at doing this job, OR you can finish college, and try to get yourself a good job.
I suppose another alternate would be you becoming homeless, and starving. Because you think it's a good idea to drop out from college, and I assume you already know your mom won't live forever, and she can't keep on supporting you.
Regarding myself, I graduated from college. I don't know why you want to drop out.
