This has really upset me, what do I do?

Okay this doesn't have anything to do with periods but I need advice. My 14th birthday was last week and in June/July I sent out birthday invitations to 37 people because I was having a garden party. I kept getting declined. Everyone was giving different reasons like holidays and just busy but I got a bit upset when no one could come. I was on snapchat last night ( when my party was supposed to be) and I looked through everyone's story and I saw all my friends having a sleepover party without me. Am I wrong to be this upset because I feel terrible about it and I feel so mad but I don't wasn't to talk to them. What should I do pleases my advice. They have never done anything like this in the past so i didn't like it when my cousin said I red to find new friends. Thank you
