All of a sudden no one answers my Facebook messages? I feel ignored.?

I messages about like 6 people on Facebook, and only 1 replied but had to leave 2 minutes after talking. He other 5 people were all online but didn't answer. It says they saw the message at a time. However they didn't answer. My other friend answers, but I asked him how to do his question and he gives me a thumbs up sticker. I question him and he does it again. I really didn't know what to do for his assignment and he keeps replying thumbs up. Everyone I sent a message to saw the message but never replied. This
Only happened yesterday. It never has happened before. They used to always talk to
Me and answer my questions. I ended up not finishing my assignment that is due today. The assignment was not a big deal since it is a not a big part of our mark. I will into trouble but will get over it. But I won't get over people ignoring me. I am writing this in he morning and school is about to start.
