Why do i feel so tied before my period and feel like vomiting don't want to eat ?

Well: The most common premenstrual symptom for those who suffer is fatigue, 93%. This lowers the stress threshold and if anxiety makes you nauseated then whala. You could target sleepiness directly with a drug called modafanil or do a standard low dose ssri. Mirtazapine may help at night in that it helps nausea, sleep and mood, read about these. With pms, sometimes tx for a short time in month helps.
