I got into the bitcoin again last year after losing all my 4.5 bitcoins to ponzi schemes early last year. I bought in bitcoin again at $20k. Now bitcoin is $6k+. I'm regretting my actions. 
Sorry for your lose mistakes is part of our lives, i think you didn't learn a out your action and decision before you can invest during the price is too expensive of you can't anticipate the surprise price dropping.
It's okay mate you can learn your mistake to avoid again this happen from you, and do not sell your coins until the price are not bouncing again be cool and be patience surely the price raise again soon.
