You gotta find better friends if you think you're 'true' friends are people who are bullies and making you cry. First, friends don't make friends cry. That's not cool, enjoyable, healthy or something that happens in a normal life. Stand up for yourself man! 
You got this!
,might as well you just wanted ti get bullied then continue, but those people who you called "friends" are toxic. They are not considering the feeling of their bullied friend, and the worst is that, they are including the parents of the bullied one, so do you think it is still healthy for you to say on that situation? Well i guess not.. You got this!
