Why are my eyes littler?

okay so my eyes have been little ever since i tried on my friends contact lens, everyone was touching them trying to help me get them in my eye, the next morning i woke up i had pink eye and ever since then my eyes have been very littler than usual. Everytime i smile they close and it doesn't look right. So does anybody know if somethings wrong with them? Do i need to goto the Eye Doctor because every morning i wake up my eyes have hard boogers all over them and i can't open my eyes sometimes?? Please help, Thanks
