Is it normal to be this way?

Okay.. how to begin.. here we go.
Is it normal that my mind is so hectic when in a relationship?
Is it normal that my feelings are so mixed about life?
I'm more motivated to do things, but at the same time I'm making wrong decisions.
I smoke weed every night, I used to be a heavy all day everyday stoner for years I quit two months ago, and started up again about a week ago.. but that's also when i hooked up with her. Well she smokes weed every night too.. but she just kinda started but now I'm smoking too.. when I need to be doing something with my life at the same time.
We have the same goals. I just don't quite know how to obtain them quite yet. im just looking for shitty mediocre jobs that will be a start. Ive worked plenty of times. none have just never stuck yet.
I guess my point is,
life is completely wasted to me just trying to live... When we could be enjoying it all.
We sleep a third of our life away... That really sucks. And now that my social life has increased my personal life has decreased and my mind is scrambled. Is it normal for me to feel so different now that I'm social?
