I’ve come to realize that maybe being a “people person” isn’t who I really am

More and more I see myself getting annoyed at the slightest things. I love my friends dearly, but something isn’t setting right with me. Every time I see someone I just want to avoid them completely and be left alone. But the thing is..I hate being alone. I try to push away the differences, but it’s not that easy anymore. I know that they are doing nothing wrong and that it’s 100% me, but I don’t know how to fix what I am feeling. I just feel lost and helpless.
