Please i need help..im worried about my unborn baby boy!?Stress...will he still be okay?

Hi you guys. So im really worried about my unborn son. I am 22 weeks pregnant and have had sooo much stress and cried and gotten so upset and sad to the point i had to throw up, i also sometimes over exert myself in hotter temperatures (my house has no AC eccept the bedroom) while doing dishes or cleaning because my boyfriend says he doesnt feel good so it has to get done so i do it and i also constantly cook meals not just for me but my baby and my boyfriend. So far throughout this pregnancy it has been so extremely hard for me. Im in so much pain ALL the time yet i continure to do all these things. Doesnt really do good to talk to my boyfriend about it because he just tell me about how he's in pain. So far ive had 2-3 times where i got so stressed out i couldnt control my breathing...well im starting to get really worried about my baby! trust me i know the risks of being stressed while pregnant but no one else is here to help me or support me. its all me! but i was wondering.....is it possible for my baby to come into this world alright and unharmed? i take all my vitamins almost everyday i almost never miss my vitamins...idk i need opinions and support here im alittle scared. i dont have family to go to and talk to about this stuff or friends anymore. Im just worried when the baby comes i have to take care of the baby, my boyfriend, my two dogs and me with no help. It would be nice to have a man be so happy that im careing and making his child inside me and pamper me and work his butt off to make sure im not stressing me or the baby and in pain as much as i am...what should i do?
