That's a good question. I'm sure that a Liberal Arts degree in Art History leads to some kind of paying position, but you'd have to look into that. It most likely means post graduate work, and if you like the idea of staying in school, you can spend the next ten years studying before you have to go looking for a permanent job. Then you can work for a museum or investment bank, managing their collections, as a PhD with a nice salary. Or you can get into restorations or archeology. It depends on your interest.
Paralegal is a clerical job that pays well because it is boring, exacting work. The more boring something is that takes intelligence, the better it pays. Like writing code for webpages, or being a tax accountant. If that's what you want, go for it. A nice safe, boring, secure life. Add a house, spouse, and kids, and you've got the American dream.
Therapy/Counseling is a far cry from Art History and paralegal. Each one of these things requires a different personality from the rest, but especially being a counselor/psychologist. There are generally two kinds of people that I have observed that become psychologists. I classify them as people that I like, and people that I think have mental problems that they are hiding. Some people have a great deal of empathy and should be counselors, other people don't, but are interested in the field. Other people have problems that they think they can solve through study and by avoiding being counseled. The teaching of psychology is trying as a profession to weed these last kind of people out of the field by having all serious candidates for degrees undergo counseling themselves.
Of these three fields, you have already in your own mind chosen which one you would go into to, if you had the courage or felt secure enough to enter. Just do it, and if you fail, so what, try again, or try something else. Would you rather be a bored paralegal in ten years, thinking "what if"? You can always make that your minor, if you want something to fall back on, or to work at part time while you get your degrees.
