I was in your very same boat and saddly I dont know if their is anything you can do. I was open with my parents to some extent but had to hide my true desire to transition. I suffered a lot of verbal abuse for highlighting my hair to the cloths I would wear. You my not beable to convince your parents to except you for who you want to be, I wish there was an easy answer. You will either try not to let it get to you to badly and just be who you are or try to get better at hiding your girl style. You are at college so you get to be who you want to be most of the time it might just have to be a trade off, you get to be you the majority of the time so its in your favor. Dont know if your family and parents will ever change and sadly you may have to deal with some level of rejection, we all do it kind of comes with the territory. I'm not saying its right, I feel family has a responsibility to love you know matter what and many time, sadly they fall short. I have a brother who was a total jock and my parents expected me to be like him but I wasnt like him and I didn't want to be like him. I dont know if you get compared to other siblings in your house hold, I did and I hated it and it was a constant in my life as long as I lived in my house hold. I would just tell you to not be afraid of being your self and you may have to either get good at hiding your self of being your self, it is your choice in the end and when you get ready to transition I would cross that bridge when it is time. Good luck sweetheart and just be free to be who you r. :-)

I hope this might help you
Find a councilor at your college that is part of the LGB community I'm pretty sure all colleges have them. They should be able to direct you on how to approach your family. I must say to prepare yourself for rejection. Because it will be a shock to them but it will take time for them to adjust even through the phases of your starting transitioning. I know your feelings almost 14 years I have been trying to transition. Until last year I managed to start. I'm still married but I must say I get physically and verbally abuse , not only by her but my children as well.
I have been told by others that you do what makes you happy its your life. Now I love my kids don't get me wrong but I want to be happy. I have had my wife tell me that I'm being selfish and you don't know what your doing. In my situation I have no relationship with my wife for Manny years as she reminds every other month. You will hear a lot of redrick but you have to give them time to adjust. They will say hurt full things to you but deep down they will still love you for who you are.

Sadly, as long as you let the fear of rejection rule your life, your parents will continue to treat you this way.

Look at it thus: what is the WORST thing your parents can do? Kick you out? Yell at you? Make you feel 3 inches tall, just for being yourself? Ok,... Now, ask yourself this: Why would you want to STAY in that situation? That isn't a loving relationship!

You're 18, you can legally move out on your OWN. You don't have to stay under their roof. Hard as it is, find a job, save up the money, and move out. I know the job market isn't the best, pay may be low, but believe me, it'll be better to move out and become your true self.

Don't let fear of their rejection stop you. Find work, save up, move out. Be yourself. If they reject you, it isn't the end of the world - you have an entire life ahead of you. Live it as who you are. You'll find other people, who will accept you and love you for yourself. That's what true family IS - loving, accepting.

Abusive "family" isn't family.
