Getting tired

I am soo getting tired of being alone. I know, I know isn't everyone? But it just feels like, to me anyways, that everyone is getting a chance to be with someone and I am just getting pasted over. I mean personally I think I am a pretty good person, maybe not a lot of people's physical attraction type, but I think I have a great personality, seriously I do. I am always trying to be positive and help people, but I have my days where I just can't handle it anymore. I like to have fun and do adventurous things but i also like to just chill at my house or someone else's and have a relaxing day. Now am I crazy or does this to me look like just a physical problem? But then again I see tons of girls, some even bigger than me, that are with somebody. I'm not asking for someone to marry, just someone who wants to want me in a girlfriend type of way. I really hope that I am not the only person out in this world that feels this way. And I don't want to hear from those girls who have offers to be girlfriends but don't take them because of some stupid reason. I'm talking about those girls/guys that aren't even getting asked at all. Please someone tell me that I'm not the only one, please. I really am not trying to be whiny or anything, I just really want and need somebody. And I would really hate to think that I am alone in the feeling. Can't somebody rescue me from this never ending tiredness that I can't seem to lose? Or am I stuck with this feeling for eternity? :(
