I hear you, because I was there.
However I learned something which turned my life around.

These are some I learned.

YOU must become the BEST FRIEND with YOURSELF.
Make a list of quality, personality, which you want to be friend with.
Try to BE on your List.
Because People and Things COME and GO, but YOU are stuck with YOURSELF for the rest of YOUR LIFE.

When you wake up in the morning, say
“I will make today THE BEST DAY OF MY LIFE.”
DO your best to make it as much as you can.

I just thought only two right now, but I will let you know if I remember some more.
