Feeling so insignificantly small and alone

Low self-esteem? Shyness and feelings of insignificance in crowds? Get a job that requires you to herd large masses of people about. Let it be a job that doesn't allow you to think. Let it furthermore be an occupation that allows for near zero training time and forces you to plunge into cold water head-first.
You'll emerge an entirely new person.

In my opinion, there's a point between needless pride and necessary pride.

Sure, you don't want to be a douchebag in front of people (needless pride), and that's GOOD. But you also have to keep your chin up and beleive you're worth it too (necessary pride). :)

I say stop worrying about how other's see you or what they think about you and act how you want, be who you want and do what you want. Sure everyone has social expectations but don't let that hold you back from enjoying your life.

As for the whole love and break up thing, all I can say simply is to move on, over time things will get better for you, same for the person you use to love as well.

You could not have explained that any better. But it is all about who you associate
yourself with. There are a lot of assholes in this world who will step on you and not
give a shit. You just need to think of all the good things you have in life at the moment.
Like your health or friends and you should be okay, Although if you have none of those I
feel sorry for you and hope things get better.

I hope you get over the girl thing.

Sticking to the original issue, I think most likely it is true that majority to almost all of the strangers around you in a crowded place may not genuinely care about you - why should they in the first place? Think of it as, why take it negatively, coz its not, its just the way it is and those people around you are just in the same situation as you - no one cares about them too, in a relative sense. If you seem to feel a need to... blend in or try to feel less insignificant by projecting an image of... you should think, why do you have to? do you have to do that? who are these strangers around you, to you, that you should care about them and what they think?

well if im just babbling nonsense oh well my bad I guess

During your life of teenage years will always be a difficult time to get through. Everyone experiences emotions and feelings they aren't use to and you have to journey through that while everything seems so uncertain about your future.

Topping that with, for you, is probably the worse thing you have experienced with your life and you will definately feel the angst of the situation.

Even knowing that the majority of people feel this way at some point won't do anything for you. Because you are yourself. Comparing yourself to other people doesn't do anything.

However, that doesn't mean advice isn't sound. While we are different people and you need to work through your own problems, people can show you paths they themselves have taken, or wished they had taken to their own problems that they feel can help you in this situation.

As for your actual situation. Your biggest problem is that you are obsessing over this girl. It's not that you are feeling these emotions, it's that you are only thinking in terms of this girl. This is NEVER a healthy situation where you can't even think beyond the girl. While you may think that love means you are only to focus on one person, that is not actually the case. Love is something that after all the virtues, after all the vices of a person. Ever fault you see, every problem you work through. And you STILL realize that you are able to not only care about her, but about yourself through the entire ordeal. THAT is when you realize that things can work.

This whole situation where you can't care about yourself because of this ordeal, that's not real man.
