Keeping a positive attitude = ignoring reality?

So I've always been a "happy" kind of a person, and it's always been my biggest fear to become like those people who say they hate their life (basically the majority of people on this planet.)  Yeah, I've always had my normal shares of problems, but I've always pushed them aside, saying happiness is something too precious to me to be compromised. In other words, in case a situation would turn up where a normal person would become sad/depressed, I would always put on a brave face and act like it doesn't bother me, and I'm still the happiest person on this planet.
This kind of belief obviously makes me BELIEVE that I am a really happy person, whether or not I have a reason to be one. This has worked pretty well for the past 2-3 years, and I have managed to live a 99% always happy existence. Whenever I've had some problems, I've turned towards the good things that I am privileged enough to have in life (music, video games, a few good friends, entertainment, sports, nature etc etc). So what if I have this and this problem? I still have all those other things in my life! I should be happy! 
 Even if my life was falling around me, I'd probably think about what I DO have and keep myself happy. The problem is, all these things now seem to be catching up with me, and cannot be ignored any longer. They're becoming a need, and I cannot distract myself any longer with the good things. The distractions are beginning to lose meaning, and suddenly look like things of small importance. 

Another problem is that nowadays I'm trying to ignore how shitty people are, and am actually trying to love everyone. Obviously, people disappoint me, and I am left controlling my anger and trying to convince myself that anger won't solve anything. Obviously, you could tell me to go a little easy on myself and give some people what they deserve, but I have unfortunately developed a strange kind of a mechanism which makes me feel all bad inside if I do that. In other words, whether or not I react nicely to people's dicky-ness, I'm still f'kd inside.
 
I guess a factor causing my current situation is that my high school's over, and there's a long break before I get into any kind of a college. This is obviously a nervy period which will decide my future, and is also going to bring about a HUGE change in my life. Also, my social life is pretty much close to zero, since there is no school and everyone's bottled up in their homes, studying hard to get into a college. It's not that I really miss my class, they weren't all that great, but I DO miss the crowd. Also, I failed to  find myself a good girl in my school years, and that's obviously a major problem.
 
So here I am, sitting at home, all suddenly confused about life. Looking for guidance and direction, and in the end just ending up playing some games to keep me happy.
At this point I don't even properly know what I have talked about. Am I saying I want reassurance that I should keep faith in life and believe it truly is magical? Or become a part of the crowd that faces reality, curses life, and lives life as he/she is told to live?  
Anyways, the thing is that I'm gonna have a tough time until August when I start a new life with college and everything, and I have to somehow survive all these thoughts in my head. Usually a very balanced/spiritual person, this kind of confusion about the very concept of life itself has got me completely confused.
Hopefully writing this LONG blog has got my mind settled, so I will go back to believing that life is great, and will go play some games to remove the seriousness of it all.
