Don't worry about it.
I was the same back when I was 16.
You can fix your social awkwardness if you want to. It's just a set of behaviours and beliefs which represent how others see you and the opportunities you feel are accessible to you. It's not easy - but it's generally just a case of knowing good questions to open people up with, becoming better at funny small talk, raising your positivity/excitedness level, understanding your market and what they want to talk about, understanding how to make confident/positive body language, and creating more opportunity for yourself (like, ask girls to hang out with you sometime or associate yourself with normal non-introvert/extrovert people.)
As a developer, there's lots that can be learnt from books on body language, game, influence, etc. But don't just do that - find a way that you can practice one thing at a time with real people. It's a practical skill and the only way of getting to grips with it is getting 100s of hours of experience.
The most important thing you could do tomorrow is to create more opportunities for things to go right or wrong. Join clubs or grab coffees and start conversations with people. Chat to people in lines. Chat to the people you sit next to. Be light-hearted and positive. Do it even if it makes your heart beat and your palms sweat.
And always be the first to say "Hey, what's your name? [And comment on something or give them a shallow reflective question that they can feel positive about when answering.]" or "Hey Y, how was your weekend?" Being the first to speak always makes you sound more confident, and it also removes the awkwardness which almost everybody feels. Find out what they're passionate about; learn to ask great questions that make people happy and you'll find out more about people, give yourself time to come up with conversation points (which is quite difficult when you're doing this for the first time) and most-of-all make everybody you meet feel less awkward.
But don't panic: chill out and take life as it comes. Trying to force things often doesn't make them happen faster; instead you'll just grease the wheels and open yourself to the changes which will happen naturally as you get older. If you do this, over time the positive aura you shine on others will surround you.
And that is how I freed myself from social anxiety.
