You are just on the bottom of the hill of the rollercoaster of life. Don't dispair though, as you are safely fastened in, and you are well supported (by us!) to safely ride your way to the top again.
Just hang in there, cause what goes down, must go up!. We have all been at the lowest point before, and we all have made it out of their. So keep chugging along and things WILL improve.
