Heres what any sensible person at the age of 14 should be doing: studying. I was given this advice when I was 14 too and yes I resented it at that time. But now I understand the importance of it. There will be plenty of time to attend parties, go on dates, get girlfriends etc in life, but at 14 it is not it.
Now to improve the situation: do what you like. Doing things out of peer pressure is never a good idea and changing yourself is even worse. Half the world is introverted, you are not alone. You have just moved in a new neighbourhood, you do not know anyone. Everyone will have problems in making friends. This is why you do what you enjoy, even if you do not make friends, at least you'll have fun doing it.
And lastly, self-pity can give an enormous high in the beginning but it'll make your life worse in the longer run. Recognize and get out of it if you are able to. See a doctor if it continues as well.
