Can one person completely ruin your life?

. Ya, usually only ONE person can screw up Your life: YOU.

It's a big world out there. I think you can avoid this witch long enough for all bad feelings to fade.

Only if the person is you! Love yourself, try to love others like her, because they are really very sad inside. Don't forget that things that seem really important today, aren't so significant when you look back on them (and sometimes they're even funny). Glad she's far away now. Get over it and move on to better friends.

leave the past and all the bad things behind and focus on the present and on the future. Think, Good thoughts, put yourself in to beautiful surroundings and look up and thank God for each new day. read the Bible and find out who God is and everything about Him, then your life will get easy and happy.

How catty. You have to distance yourself from this girl & her line of fire because it sounds as though she will stop at nothing until she has wiped you out. She obviously is threatened by you & your best bet is to be happy & live your life & show her how good you're doing without her & she will hate that she doesnt have an impact on you anymore....

Yes they can. Some people act like the plague. You have to get them out of your life.

that's happened to me. it's like guys, just let it go... you'll get over it and you'll have days where you don't even think about her... the way i saw it, there's way too many ppl in the world, so you can't just worry about one, AND there are ppl out there who have more enemies than friends. at least you're not one of them.

sounds like crab-mentality, where she pulls you down if ever you become competitive with her. You need to forget about her and find a new best friend.

If you don't live near her i wouldn't even worry about her.
