Your relatives were mistreating you bc of your stuttering even though you are their kid? That's a severe issue which actually contains serious family dissension and you gotta talk about it with your relatives and if it fails it's time you move out of your family. When family is not famly it's best to move out and live your own life. As for your occupational obstacles led by stuttering, since both you and me are into art(the only discrepancy may be that I also like science LOL), I suggest if you really can't find a job offline you can try taking some jobs online from forums, groups, etc. I think to some degree that can help you cope with the survival barriers.
