Nona, right now your weight might seem like the end of the world, but I promise you that there are more important things for your potential college friends to care about. (And if a guy cares that much about your appearance, don't date him, he'll just make you feel like shit.)
If you want to lose weight for your health, mental or physical, go for it. But be careful and slow. Generally 0.25-0.8kg per week is a reasonable weight loss goal depending on your starting physical health.
Step 1 is just to built up your muscles. Make sure you're exercising with proper form. Take a walk every day. Drink enough water. Once you've started being healthy, and building habits, then you can focus on actually losing weight. It's not about instant gratification but instead constant effort to an overall goal.
If you focus on trying to get as slim as possible as fast as possible, you WILL develop an eating disorder and wreck your metabolism for years if not your whole life, as well as make yourself constantly constipated, nauseous, irritable, stupid (bad for college), your hair will fall out, your nails will get yellow, and so on.
Just take it slow, that way you'll look back in a couple months and go "wow, I've made good progress!" instead of "wow, my life was so much better before I was addicted to starving myself"
