There is this boy named Lucas and I have liked him since kindergarten. Today I just found out that he has even going out with my best friend Ella! I feel like killing myself (or Ella) what should I do!?

Ok. First of all, if u have thoughts of suicide (killing urself) then u need to tell your parents IMMEDIATELY. And u should also contact a therapist and a doctor to help u... 2nd of all, I don't think it's right to commit suicide or murder, over a boy. There are many fish in the sea! :). Third of all, if it really bothers u that ur friend is going out with your crush, just calmly tell her how u feel! How u feel about Lucas! Just tell Ella that you don't think it's ok that she is going out with your crush (but don't start yelling) the calmer u speak/act, the more Ella will be more understanding. Hopes this helps! Chat with ya later Jane! :)

I agree it isn't okay to feel like killing yourself over a boy. But it is okay to be sad. I know EXACTLY what it feels like to like somebody who has a girlfriend. But remember it's just a crush, and you'll eventually move on and meet somebody else. hope this helped. If u want to talk, message me. :)

ok first off, NEVER kill yourself!! And don't kill your best friend, either! I know this sounds impossible but you HAVE to talk to your parents! I used to be shy to tell my mom but once I did, life was SO much easier! If you tell your parents (which you should) say something like this to make it less awkward:
Hey, mom. Can I talk to you? So, there's a guy at my school named Lucas. I guess he's sorta cute. I don't know! But, I guess I kinda like him, but the worst thing happened. He's dating ELLA! I'm sort of mad at Ella. I know it's not all HER fault, but you know sometimes you can't just help but be mad at someone. I know I don't usually ask you for help but I just wanted you to know. And maybe give me a little help?

Hope you find this advice helpful!

I'm pretty certain that this incisive feeling to murder is just jealousy. But don't resort to that, haha. :)

Honestly, if Ella dating Lucas is still bothering you, even right now as you're reading this, talk to her about it. If she really is your best friend, she'll listen to what you have to say. If not, try and forget about Lucas; there are plenty of other boys out there.
Second off, if you don't feel comfortable enough to talk to Ella about it, talk to your mother, or some other trusted older woman who's most likely gone through similar things. She can probably give you better advice.
And (I read your response to the first person who gave you advice) if he continues to make feel so jealous and angry that you start to cry, he isn't worth it. You seem like a great person, and I'm sure that there's going to be another boy out there who will see how amazing you are.
It's hard to forget about a boy you've liked for a long time, but it's possible. Try to get involved in some sports or a different kind of activity to distract yourself. If that doesn't work, then just try talking to your mom or someone who's gone through something similar.

Good luck :)
