anxiety

So I finished a 22 day Master-Cleanse on feb 15 and lately I feel like i have been slipping. I feel like i have gained back everything I lost, I feel anxiety, panicky,, not nearly as awesome as I did while cleansing. is it too soon to do it again?
anyone else feel like they reverted back to old ways shortly after, perhaps had a "meltdown" or Depression after?
I feel very bad,

plus my period is all screwed up. havent had it since jan 22
