Too much social networks?

[Jessica]

Well, keeping in mind a majority of these where created when i was little, i know its my fault... I have so many social networks! And I'm being legit here. I typed my name in twitter, and found 12 accounts belonging to me. I have like 4 bebo accounts (when I used it) and about 6 face books. Not to mention unused youtube accounts, and I all made these when I was like 9-12. I'm 13 going 14 and realised I was an idiot! I don't know why I had all these. I type my name into google and so many pictures of me show up and I hate it! I don't know what to do. Is this a bad thing and I'm just over reacting or is it serious stuff? And is there any way to delete all these accounts? I can't get back into them. I was always a smart Internet kid so making the accounts wasn't the problem. The problem now is I can't access them to delete them. -.- any help/advice?
