Scared..af

Ssooo...Im 18 jus graduated from high school and started community college , I was living with my Grandaddy at first but it really wasn't working out he was arguing with me almost everyday abt nothing he was trying to control me and never listened to anything I had to say like I was 5yrs old or sumthin he belittled me telling me I had no one on my side but him and he ridiculed me for my having a job when he said he would get me a job thts the mane reason I moved with him in the first place. So I decided I didn't want to argue anymore and I didn't to destroy out relationship anymore than I already had but my family isn't good for me and as much as I love them I love me more ; so I packed my shit and moved with my bf, i still go to school and i have a job waitressing at this restaurant moving away from my family for the first time is ssoo scary and being with my bf is so wreckless cause I dnt kno where it could go we could break up at anytime then I'm out on the street I'm jus scared cause I really don't know what's gonna happen idk if the decision u made was the right one but...I cnt go back
