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. 
Hi Romeoetin
I have friends who bought at 20k, too.
Its not a shame. Money is unpredictable.. so is Bitcoin.
Just make sure to dont make the mistake again and grow from this situation.
My advise... listen to your feelings, if you feel overwhelmed with feelings, calm down and observe your breath
And go on from there.
You will grow from this!
