I am so sad about my party

So, i dreamed for a big pool party for my sixteenth birthday. I have informed my guests more than a month earlier and i had positive answers. It ended up only 20 people coming out of the 60 i have invited. Also about 20 people have not answered at all! I am so sad about it because i feel that everyone hates me for no reason or they are just bored of me. The party was excellent and everyone has enjoyed though. But my expectations are dead. I just thought of writing to let my feelings out... I feel so ashamed that everyone knows that this party was such a fail in term of people coming. 😢
