Should i be sad or not?

I feel heartbroken . Cant i love the girl that i want? The girl thats always been there for me ? I dont give a damn if she says that she cares for everyone . I only know one thing , i want her , i love her , i need her , i miss her . Why is there problems and gaps that happen when i want someone badly ? Cant i just get over it ? I wish i didnt know anyone , shouldnt have talk to anyone and focus on being with my dance mates , my school friends and my best neighbour . They are the ones that make me forget bout the problems that i have . I don't want to keep being emotionally sad as its very irritating to me but still i kept thinking to much . The truth is if i cant get you , i will cry my heart out if possible . Why must the person i love say that she wants me to be happier with that other one . Haissss , i'm so freaking angry . Cant you understand that i love you and that i want you . Nothing can stop me from loving you , its my choice . I wish i have the guts to say all this , but in the end i'm avoiding , just talking to you happily . I like it when i see you happy , you're super duper cute . Everytime i think of you , i would smile to myself , sometimes my mum would caught me smiling to myself and its like wth . Anyways i just wanted to say all this out , i really feel like its the end of the world to me . Maybe my neighbours right , everyone one of us is falling apart due to a species called girls . Haisssssssss . I think its really true , all my shuffle mates are not meeting me often because they wanna be with their gf and consider them more important , but no matter what , i will still be there for my friends . for better or for worst , friends are what we need .
