No education,no license or car. No job. Super stressed out. I am 18 years old. Isolating by myself, refused to hangout with friends or go anywhere.
18 years is not the end of life. You've got a lot of opportunities ahead of you. Just don't focus on what you've missed, but think about what you want to achieve. It's positive thinking that's the key to solving your problem. I know it's hard. A lot of regrets torment me every day - the wrong place to study, a lot of laziness, loss of time, low productivity, no girlfriend, or reliable friends. I understand that feeling. But I also understand that life has just begun. And holding on to regrets, you can drown in it.
I would advise you to start with mental health - deal with your stress, make a pleasant rest, find the motivation to move on, set a goal, and start to achieve it with all your efforts so that after time this goal also does not turn into another regret. This is the only way it will work.
And also take the time of self-isolation as a necessary measure for the future. Dedicate this time at home to yourself, spend it as productively as possible. Time to communicate with friends will be enough in the future, but there may not be enough time to take care of yourself.
Think positive! I hope you'll get better.
