Is the feeling of excessive joy after meditating a sign of emotional instability?

Kabhi kabhi meditation ke baad mujhe zaroorat se zyada khush hone ki feeling aati hai. Aisa lagta hai jaise main manic state mein hoon aur control kho raha hoon. Kya yeh emotional high meri mood swings aur mental health ke liye galat hai, ya yeh aasaan tareeka hai khushi ka? My name is Neha, born on 18th May 1997. She was born at 4:00 AM, in Delhi.
