I can't handle this anymore....

It started when I was in 8th grader. There was a girl I have crush on but she falsely accused me of molesting her and I couldn't able to defend myself and my parents didn't believe me either because of that I ended up going to juvenile centre for 1yr, I was bullied everyday.

After I was released everyone changed around me they treated me like a criminal

I often see my family happy when I was not around them.

I am 11th grader right now and today that same girl gave me a love letter. I don't if she doesn't Recognise me Or it was a accident because there is a person which name same name as me and he sit in front of me.

Right now l look horrible even I can't able to identity my 4yr old image.

Any advice to handle my life
