Should I build my life alone in the West after divorced?

I’m an Asian was married to my now ex husband. After divorce, my in laws are offering me to stay in the country for my future because I have a diploma. I can extend my residence permit but I am confused. I am scared to start a life alone without a mahram. Additionally I am sick and perhaps no one would take care of me if I stay. On the other hand, there are many opportunities for my career compared with my own country. If you were me, what would you do?
