Depression

12 weeks of pregnancy..Start to feel depressed....can't eat well (always vomit) and cant sleep well at night (always wake up in the middle of night). No mood to work, superior always give alot of pressure at work place, keep complaining i always take leave + mc and ostracised by all the colleagues. HOD giving unfair treatment, example everyone in the dept/unit entitled for the "special thing", only i don't have, purposely don't give me.... ?
