Hi, keep yourself together the things will get a lot better. You are in such an age where you feel like everything is bad, but it really isn't. First of all, you have to study and work on things that make you happy, find your real passion. Friends will come with time, but all you have in the end is your skills, don't forget this! It is more important than friends because skills are what you make you and build you as a person, and is your priority to like yourself. To achieve this goal you have to put in a lot of hard work, and you will see that your self-esteem will get much bigger. Start being active, physical and mentally. Don't drop out of school if you like your subject, just work harder. And don't worry about the jobs, there is always going to be a job out there! With your achievements, your self-esteem will go higher and higher. That won't come immediately because you are young will come with time, so don't give pressure on yourself. The first goal is just to discover your passion and what you are willing to invest your time and effort in! That's all. Excuse my bad English.
