I haven’t been feeling like myself lately

I got a new job and I’ve been working there almost 3 months. It requires a lot of work and me having to wake up at five in the morning almost every day. I didn’t realize that I was going to be so stressed over this job that seemed so easy when I applied. But anyways ever since I got the job I felt like I lost sight of who I am, what I want to do with my life and how to deal with the fact that I still want to be in a relationship with my closest friend. Like I said the job requires me to work almost every day I really don’t have time for myself because I help my mom out and I babysit ever Saturday. I really don’t have any me time. What do I do?!?
