so stressed out!

I'm 20 years old and 14 weeks pregnant. I'm Sick of living with my boyfriends parents, they make me feel like I'm an inconvenience to them. I'm stuck in my boyfriends bedroom all the time, my mother has offered me to move in with her but my boyfriend isn't comfortable with that. I have 10 points on the council list so can't get a house yet, even though I've given evidence that I'm pregnant and at risk of homelessness my points still haven't gone up yet (you need about 70+) I have literally 1 friend that I never see, the rest haven't bothered since I found out I was pregnant. The only plus side I can see is that I'm going to be a mother to a beautiful baby. My hormones are everywhere I'm going mad and I'm worried I'm being violent because I don't like that sort of stuff, especially in parents! My boyfriend is supportive but by fuck does he get on my nerves!! I can't give up smoking no matter how hard I try!! I'm worried I'm going to fail. What if I have a mental illness from being so stressed all these years and I don't want my baby to be the same. My secret is getting out that I'm pregnant. I wanted to wait till Christmas Day and by then I would have found out the gender. I have people talking behind my back about my pregnancy, saying I only did it because my "friend" got pregnant and I did it as soon as I found out, which isn't true because I knew I was pregnant before she did. And it's so so petty but so annoying! And I know what people are thinking, we ain't good for each other because every time my boyfriend drinks he has an awful attitude towards me, and then we end up arguing and all his friends get involved. I think he's too embarrassed to tell people because he's only told 1 friend and he didn't even want to do that. My boyfriends mother is literally a bitch all the time. She's making comments about me and talking behind my back to my SIL. saying I'm a living sin because I'm not married, I'm not old enough to be a mother, and I'm stuck under her fucking roof! Yes I pay my way around and do my bit, I cook for everyone and don't get shown any appreciation by anyone! I'm sick of it.
