You don't need to question your life choices, especially when you are so young. Let's face it, you haven't even graduated from high school yet. And even then so, any problem you face in life can be resolved, even if it doesn't seem like it can. I greatly recommend you talk with your family, friends, or someone you can trust in general, since they know you much more better. And even if you don't think they can help you, we're here for you and care for you. If you need to cry, go ahead and cry, since no one would judge you.
