How to prevent myself from crying too much?

I believe in God and my faith tells me that there'll be a breakthrough in my life, but at times I still find myself cry over my lonely life. I am a very outgoing person, but ever since I had to move abroad for a further education, I don't have a social life anymore (even though I am still the same fun girl infront of my family). Sometimes I find myself pitying myself and crying on the basement. How to ure myself that my life really is going to change one day if only I could just be patient and put all my worries in Christ?
