If you're just interested in law because you're looking for something new, it's probably not a good idea. It is an extremely arduous journey you have ahead of you, and it is a huge mental, emotional, and financial investment.
Don't be depressed. If you want it, then go after it. Only you know if something is right for you. Just be aware that law is probably the worst field to go into if you just 'don't know what else to do'.
