Mood swinging~

I don't know what is happening within myself.
Its feel very weird and awkward.
I don't like this kind of feel.
I accidentally upset my friends.
I don't really mean it but I just don't know why!
Mood swinging within me had become worse than last time.
I'm still in the progress to reveal the answer.
I hope I have the enough time to figure it out before anything goes on.
I'll do my best to control my own mood.
