I'm way too pathetic for my age

I'm fairly young here. 16 years old. Dropout of highschool for a year. Depressed. No friends. No social skills. No hobbies. Adults keep pressuring me to go back to school while not believing I have mental issues. Everyone thinks it's just normal teenage behavior and "it's all hormones fault". I'm being looked down by my own parents despite I used to be a gifted kid. I'm a total loser that no one wants to be around. My family isn't financially stable and as the eldest child I'm a burden. My dad is in his 50s and he's the only one who works. I don't know why I was born. Maybe I'll be working on getting ged next year because it's the only way to get a decent job in my country. I don't need advice. I've tried everything I could.
