So, I just turned 17, 4 days ago, my problems are that my parents divorced when I was 4 or 5, I can't remember. Since then I've been living with my mom, but lately, ( this 2 years ), I feel more than often sad, maybe because my mom is still single. She is great, but she doesn't believe that I will make it in another country, she always says to drop it because there is nothing waiting for me anywhere but here. She also tells me how sick she is and that one day she might not be here anymore. I mean, isn't enough that I didn't knew my dad, now I have to live with the constant fear of losing my only parent?

One part of me is excited & happy because I'm going to college, and I'm going to live my dreams. But the other part is depressed because I will leave my mom here alone :(

What should I do ?

I think it would make your mom happy and proud for you to attend college. Do that.

You grow up and live your own life, you tell you mom you love her but that if she continues her guilt trip you will have to limit your communication with her. Tell her that she needs to get out, make friends, move to where other family is at. One does not have to marry to be happy.

My older kids and I laugh now, my mom for 30 years would tell us this may be her last birthday or christmas or easter with us, She was using guilt to try and control out lives, in doing it, I did not even speak to her for 5 years, she made two of the grandkids move away and have little contact except when they wanted money from her.

As for as dying, yes she will one day, it may be tomorrow, or it may be in 30 or 40 years no one knows.

If she says her health is bad ask her what is it, has she been to the doctor

Yes, her condition can't be improved just stopped or slowed down.
