Im pregnant but im a being a bad person and what do i do?

This will either sound really selfish and stupid or serious. Idk. But i found out i was pregnant a couple weeks ago nd now everybody on my side of the family and my boyfriends knows. Well his mom jus died of cancer on the same day i confirmed my pregnancy... Well she had told everyone before she died i was pregnant. She also said my boyfriends sisters 13 yr old daughter who has a kdney disease and only one kidney is pregnant also... And it may be by a black guy i personally see no reason for their reactions to that but thats not the point the point is is i feel jealous because mr and chris started trying for a baby and everyone was shocked and told him he needed to stop havin kids well that hurt my feelings because he has 3 but this is my first and im realy happy or i was til her ordeal overtook my news...i feel forgotten and my unborn child is forgotten and i dont know how to deal with the jealousy or the fact everyone tells him he needs to stop having kids when im not gonna have just one baby. An i love him. I want to be with him forever and for him to be a father to our child but my other problem is he drinks beer alot. Not as much as he use to but he does and it really upsets me. I cant make him choose between drinking and us not becuz im afraid of what hed say to me but because he will ve a father to my child. I jus dont know whatto do about all my feelings and its a lot to deal with :'( not to mention i cant seem to get the stupid medicaid people to do their job so i can get to an obgyn and make sure my babys ok im almost 3 months along but i dnt have $500 and they wont do their job! Its been 30 days already �im losin my mind and idk what to do!! �
