Well.. I'm not an expert, so I cannot say everything I say is true.
It seems that you were overwhelmed by a stressing pressure in your mind.
As for anyone that is bothering you:
Internet - The safest thing you can do is ignore them. Some people don't understand that what they say can make one suffer or care about others because of the lack of being shown compassion in their lives. If you feel comfortable, ask them nicely and powerfully how they are making you feel and what it means. If they respond inappropriately, tell them you wish they could understand and tell them how you'd care if they were in pain. At least, that is how I would respond. You could also just end the conversation, but that is entirely for you to decide. If you respond with something hateful or.. informal, they will not take you seriously and continue doing what they are doing.
In Real Life - I do not have much to say since.. I've been anti-social for quite a while now, and not by choice, but I would just say to try to find someone who can understand how you feel and try to help you. They are bound to calm you down when you are having trouble. My mother told me that in your life you are going to have people who push you and it's your job to not let them. You shouldn't let people discourage you because they don't believe in what you do.
That is all I can say and if you had a specific question, go ahead and ask me.
I apologize if I missed something.
