single mum

hi, i'm a newly single mum of one living in northern ireland. i'm from england and want to move back there. i'm self employed and it wouldn't be possible for me to move my business therefore i'll have no work initially. i'm wandering if anyone could give me any guidance/info on what help i would get or what i would be entitled to regarding housing and benefits etc. i would really appreciate some help as i find it all abit confusing when trying to find info online regarding this. thanks!
