May the Lord, Jesus Christ, bless and comfort you. May He be your light always. In Jesus Christ's name, amen.
I do not know if it is the same, but when I was just a little younger than you are now, I had a very similar spate of what you are now experiencing. I know it is very real, but I also believe it may have a lot to do with the time of life and what the mind and body must endure to grow. It is not very nice, but the Lord got me through that rough patch, and I believe He does the same for all of us. I pray God uses this information in comforting you.
