Hi Katie and welcome to Susan's, i agree with everyone, keep your grades up so you can get a good job, transitioning sucks up allot of cash. Things you can do now... Hummm let me see, no cash to get your facial hair removed, you can do that when you do have money ,but it should be top on your list, you can start working on your voice, this to should be at the top of the list too as it can take years to perfect it, Google voice and you will find allot of free resources, Start growing your hair but depending what on your major is you might have to cut it when you get a job, depends on the company and how strict their rules are.
Some college's have a gender program, never hurts to ask. You will need to see a therapist to help sort out things. Since you are about finished till the fall maybe you could try to get a part time job, any kind of job to bring in some money.
HUGS
