Really need advice on how to deal with a troubled friendship?

Ok..so this is going to be long. For the past three weeks...I have been in great emotional distress. There is two brothers..one is 18 and one is 14..and they have been my absolute best friends for the past two years. We were incredibly close..they considered me a part of their family and I considered them like my own brothers. But unfortuantly..their mother is a big drama queen. Their mother comes up with problems out of nowhere that no-one else was even thinking was a problem. I would see them and talk with them three-four times a week. And apparently..their mother started to see this as a problem. Even though she acted like she was very approving of it. One day..about three weeks ago,on November 6th. She emailed them and their dad(divorced) that I "have been hanging out with them too much and they have failed to show to limit this type of behavior". Their dad fowarded me this email..saying to both that he does not know what to say as it does not seem to be bothering them nearly as much as her. Now this is where things got ugly. I took it waaaaaaay to hard...and i was waaaaaaaay to over-defensive and over-sensitive. I realize this now. I emailed her back...like 8 times...trying to "defend myself) and boy oh boy she took it in the worst type of way..and started blaming me of all sort of stuff that before she did not blame me of. She blocked me and her sons Facebook from me..blocked me from all fo her emails..and told almost all of my friends that were connected to them in any way to delete and block me. Apparently..the mother is convicne that i hacked the younger brothers facebook and hacked all of their emails and have been stalkign all of her friends(the younger brothers facebook was hacked a few days earlier) This made me go nuts. I was emailing and calling them several times a day...with absolutely no response. Until i finally contacted them through another friend. Apparently..the older brother knows i have not done all the stuff the mother thinks i have(i dont know why he could nto just tell me that,instead of making me incredibly worried and sad) but still thinks we should take a moth or so break from each other. The younger brother though...unfortunantly..is completely convinced that ii hacked his Facebook. I have known his email pword for the past year or so..and when something went wrong wit his Facebook..apparently he is blaming me purely based off of that. I am glad that the older brother still wants to be friends. But I have no idea about the younger one...he had never talked to me about it. I have No idea if he is mad or not. He just wont talk to me about it, And i REALLY like him. I realize that this is my fault for going nuts over it and being overdefensive and over sensitive. I told them that I realize this. I have not contacted them for two and a half weeks now. I feel like he does not like me anymore and this friendship is forever damaged if not destroyed. Even though i very obviously made it clear that i am VERY sad about it,,,they seem to just NOT CARE at all. Which makes me fell i am unwanted and mending the friendship is just pointless. How to i mend this friendship and let things get back to normal...what should i do. I know I have done wrong..and boy oh boy i have learned my lesson.
