Ive noticed with my own chess playing that I get peaks and valleys. Sometimes I will be on a roll where I will be really strong in my chess games and I will keep winning game after game and then sometimes I will be in a slump where I will keep losing and where I will make mistakes that would get me in trouble in my games. So with Chess I get peaks and valleys. Good times and bad times.
Yes, it looks like you had a paticularly sharp decline just last month when your blitz rating fell from 893 to 163 in only 5 days. Losing 38 in a row must have been tough.
