Wait whats going on⁉️⁉️ Am TILTED ⬇️250+ rapid rating points my new ELO sucks!!!!!🤯🤯😤

how is is this even possible to lose this much rating points in matter of days

It's not that bad.  You were rated less than 200 just about 2 years ago.   

And by now am supposed to be 2200+ just by looking at my progress curve

What happened?

Nobody increases their ratings forever.  Everyone has to plateau at some point.   

And it may just be temporary.  If you are trying to incorporate something new,  it is normal for ratings to suffer.

When did you make the Legend league?  Have you changed how often your were playing since you made it?   It looks like the number of games you have played fell off.

I see the OP is playing a lot of 3/0 Blitz and 1/0 Bullet; do you think that could be the root cause for stunting his rapid rating?

Lots of 3|0 and 1|0 games alone are actually not sufficient to cause the damage. More likely, UmarBadeko is entering a period where his opponents provide slightly more opposition than what their ratings would suggest,

Like JBF noted, for the overwhelming majority, the peak playing strength of a player does not correlate to their overall playing rating. A peak rating just means that a player has achieved a maximum rating, but I believe that UmarBadeko has an average playing strength in the order of around 1850 to 1900.

Unlike the majority of your rapid games which are played using the 15|10 control, I notice that most (if not all) of UmarBadeko's rapid games are 10 min which are, in my opinion, not too far off quick blitz timings, so 3|0 games and 1|0 bullet games won't impact his games too much.

Maybe it cause I have been playing a lot of daily and less of rapid and trying to switch my repertoire at the same time

Switching your repertoire naturally causes a drop of usually 100-200 points I find, but it could be more. It is temporary and in a few months, you might recover as your new repertoire becomes more comfortable. 

If not for repertoire switching, then the reason you dropped so much might be tilt, but it might also be burnout (which can be aided by taking a small break from chess) or normal rating variance or even other non-chess factors which impact your play such as lack of sleep or lack of nutrition. 

In the meantime, this blog post of mine (about a year old) might be relatable for you in some ways and if not, then hopefully at least inspirational in others:

Then I'll be grinding hard to get to my all time high and eventually get past it
