What am I doing wrong I dropped 100 elo
It's not at all unusual to have periods of steady improvement followed by periods of stagnation or even back sliding. This is true for a great many activities, not just chess. I have fallen approximately 400 rating points in 10 days, then after a period of futility, gained much of the lost rating back. In this type of cycle, your playing strength eventually settles somewhere significantly above your old max, but well below the highest before you succumbed to backsliding.
Wise words, Badger, and I'm experiencing that right now. I blundered 4 times in game against a bot (which lacks time constraint). It's been a downhill slide for several days now.
mDSABi_T, for me, the more I worry the worse it gets. It's our minds that defeat us, not our current skill or lack of. Hang in there; it'll pass, I'm sure of it!
Oh my gosh! I just watched a video on How To Analyze Your game (suggested by @doctornukem) and I think it will help you (it certainly is helping me):
