You are 18 its there possibly other relatives or friends you can stay with for a bit? Even now at my age 40plus my parents and I can't get along when living in the same house but get along great. Something about parents that when their children reach adulthood they still consider them children as long as they are living in the family home but like magic or something when they live other places they treat them as an equil. Still haven't figured that stuff out other then the fact that my parent and I get along fantastic as long as I don't live with the parent.
