I've been having suicidal thoughts...

I am a 20f who feels like she's wasted her adolescence. Now I've come to reddit for help. I ask that someone reads my story (I'll keep it short and simple) and tells me if I'm just being overdramatic, or this is reason to feel depressed. I spent most of my adolescent years lallygagging or playing video games. I would say that my attendance at school was less than 10 percent, and that's what hurts me the most. Growing up, I realize that education is one of the most important things in life and it's something that I lack. I also do not have any spectacular talents or abilities. Another thing that deeply hurts me is my inability to make and keep friends, up until now I've had no one. I'm an uneducated woman with no friends or future.
