I'm sorry that you haven't been supported by your family. No-one should have to go through that. Ultimately it is your decision what you decide to do with your life. Psychology can be a great profession but I also strongly believe that you need to be able to manage your own emotions before being able to help others. But with that, even if you aren't in a place now to study psychology it doesn't mean you won't be able to later if that is your area of interest.

Do you need to choose your major straight away? Would it be possible to take a few different elective classes in the subjects you are interested in and see what you enjoy and do well in? That is often the best way to work out where you are at, what you enjoy and what you can cope with.
