Get your own shit together.
Why did you drop out of school? Was that High School or College?
Have you any idea what career you would like to pursue?
The most important thing you can do, at your age, is to determine what it is you would like to do with your life, and then ask yourself, 'okay, what's one thing I can do, THIS WEEK, that will take me even ONE SMALL STEP CLOSER to that goal?'
For example... if you wanted to be in television... it would be better to take a job sweeping a local news stations floor, than to take a higher paying job working the door at some club or any other totally unrelated job. Working at the Station you are at least meeting people In that industry.
As to your social life... if you are not in school, then your next most likely prospect for long term friendships is your job... so, again, the more effort you put into your career, at this age, the more likely you are to find like minded people with which to hang.
And as to romance... women are attracted to men who exhibit self confidence.
Some men are masters at faking it... others have it without any actual thing about themselves over which to feel confident ( which is actually called arrogance )
But most of us will not attain nor exhibit self confidence until we start experiencing some success or at least are seen by our peers as COMPETENT at something, anything.
If there is an area in your life in which you feel competent, then you will do best to play that up in a setting in which women will see that in you... for example... if your a Star Wars nerd who i confident in your mastery of everything Star Warsish, then got to sci fi conventions and comic-cons. Your best bet is a needy girl who thinks nerdy boys are cute.
If you happen to be a good dancer... that is a rare skill among men, go to places where women want to dance... your self confidence in your dancing will make them say yes when you ask them.
If you are a fitness freak... then you might want to try for a job teaching a fitness class to women and men. Women at the gym are going to find a really fit, and knowledgable trainer attractive... especially if he is a little shy and not so full of himself as those men who are more concerned with their appearance than they are with anything else ( Mirror hogging Gym Rat behavior is seen by women as a FEMININE trait... i.e., not really manly )
And if you don't HAVE any area in which you feel self confident, then, again, your best bet is to find something in life about which you feel passionate and get yourself involved in it, be that your career or your hobby.
getting your own life on track, having some small measure of success and direction will result in your exuding a competency and comfort with yourself that will make others want to be around you, to spend time with you.
Lose yourself in something you love, and love will find you.
