How to cope with this new lifestyle?

I have been on my own for 2 years living with my boyfriend at one point and with friends at another time but I had to move back home recently due to my bad life choices. I used to live a very fast pased life in a big city, always partying, always with my boyfriend, always surrounded by people and friends, always had money though I never worked. . My life was very very fun and illigal. Now that I am back at home, my boyfriend is in jail and I am liveing in the middle of nowhere in a small town 3 hours from where I used to live. I dont have many privledges and no acsess to transportation so I do not have many friends. I have my mom always getting mad at me and my step dad ( this is the first time I have ever lived with him scine he came into the family ) always placeing rules and being in school plus working its very stressful. My fun days filled with kissis and laughter, fun and love are now replaces by stress, work, sternness and reality. I am very lonely and I cannot seem to cope. I know this life style is much more productive and better for the out come of my future but I have been doing this for 4 months now and I already feel like I am just fadeing away. I feel like I have lost myself and I am looseing hope. The worst part is that of the 2 years I lived on my own 1 of them I was homeless with my boyfriend but guess what?? I almost feel like I had more fun when I was homeless. I do not know if I miss my old life style or if I really just miss my boyfriend. I think I am liveing a lie and I may be going mad.. What can I do?
