<human>: Can you condense the text into three sentences or less?

I've been in a relationship with this guy for almost 2 years. We're totally great together and we're always having fun! He's so great to me and he makes me happy and I feel like I can't live without him. (By the way, I'm 16 he's 18) We both are very happy with each other and love each other equally. Recently, I've been getting upset because I keep having the feeling that I want to break up with him. I have no idea why. Sometimes, I feel extremely happy and when I'm with him I don't feel sad, but, more often than not I've been feeling sad because I have some feelings that I want to break up. 

There has been a lot of things happening in my life recently that have been making me stressed out, for example, my father is an alcoholic and a drug addict, and my mom is struggling with depression and going off her medicine. They are also probably getting a divorce but I'm not sure. I've been really busy with multiple activities I have after school and trying to make things work with every thing. I also keep thinking about death and what could happen after death and it makes me feel depressed and everything is happening at once. I thought maybe these things could contribute to how I feel. 

I've talked to him about how I have these feelings about him and we've gone on a break but we ended it because I started to feel happy again and wanted to go back to him. But recently, I've been getting bad feelings again. The feelings go back and forth, probably every other week.
Could someone please help me and help me figure out how I'm feeling and why and what I should do?
