Depression during pregnancy

Hi moms, I’m a first time mom here juggling my degree, work and daily house chores. Unfortunately, I do not get the support from my husband who’s supposed to be there for me during this time. Instead, I’m being treated like a maid and expected to do everything like normal. I can’t quit my job although teaching has been honestly tiring. Not forgetting the countless going up and down the stairs. Often, I find myself crying because I’m stressed out at work and home. I can’t have proper sleep at night because my husband snores and refuses to do anything about it because he says it’s natural. On other days, I’m being manipulated into having sex since he says “it’ll help me prepare for birth”. Of course, I don’t fall into the manipulation because how can I? I’m tired from being a teacher, I’m tired of having to take care of the household chores, and I’m tired of having to provide for a man child. I don’t know what else to do and my mom is not taking me back because as the old people believe, the wife belongs to the husband. I lost sleep. I lost my rest time. I lost my happiness. I don’t even have any will to live anymore.
