I has cancer

[Quan]

Thank you all for your support, as always!
You are lovely.
I want to talk about some energy symptoms that are happening lately.
As I already mentioned, for about the last two weeks I am eating very light food and little food, compared to before (I am not so hungry and it comes naturally)
And I have those states of almost spiritual ecstasy where I am so filled with love and awe and in tears, overflowing with grace and gratitude.
Afterwards or rather, the next day, it is often some sort of backlash, where the mind is extremely active and tries to insinuate what might happen, etc. and I am very agitated and cannot find sleep, despite being really tired (yesterday was a really wacky day energetically, probably accentuated by the full moon and the wind storm ). And then after that, when the mind sort of has shot all of its arrows, there comes a period of relative calm (that is the state I am in now)
Has anyone experienced similar?
My own interpretation is that it is the mind or ego that wants to regain control because it feels threatened by spiritual high-vibrational states.

Thank you for letting me support.
Yes i know what you mean just let the body feel what it wants and let mind comment how it wannts on these states while you step back. There is much greater peace beyond the two, the up or down both are two sides of same coin.. 
2 things come to mind, the observer observing the observer.. or 3 statues of buddha- statue of buddha mad  -confronting ego self , the happy/laughing buddha feeling such bliss then the serene buddha moving beyond the two- of course its not linear you can cyle between each one.
