Could stress be a cause of my hair loss? Please help!?

Ok so here’s the story, in the past year I’ve had 4 different jobs (from moving around), moved out of my parents house about 60 miles away to live w/my boyfriend. The relationship doesn’t seem to be going well, I don’t feel like I fit in at my current job I’ve been at for about 4 months. I don’t sleep that well anymore. I’m worried about money, going back to school, etc. I’m only 20 years old. My hair has been falling out a lot more lately for the past 4 months or so. It seemed to have started AFTER I stopped birth control pills, but I’m not going back on them for my own personal reasons. My hair cutting lady even said my hair is very thin (and they normally say it’s thick) So my question is do you guys think I sound stressed and could this be a factor in hair loss? Please no rude comments I’m really scared about this.
