I made a mistake and lied to my girlfriend. She told me she never wanted to see me or talk to me again. This girl is the only girl I have felt this way for and I cannot stop thinking about her. Right now she is now talking to me but it only about how mad she is at me and keeps asking why I did it. Please help me. I'm extremely depressed!

Hey, take responsibility for your lie and take the consequences.
Buck up and take it. It will all eventually go away.
The best thing to do is to forgive yourself. She will possibly forgive you, too, but that is not the most important thing. You lied for a reason. Ask yourself why you lied? You may have been trying to get away from her?
At any rate, it is not the end of the world but the start of you getting to know your real intentions and learning from that.
Stand and be true,

Your upset? You just hurt her by lying and why wouldn't she be mad at you? So many people play games with their relationships and when they are with someone special then they manage to screw it up-possibly on purpose due to being scared or having cold feet if the relationship is getting too deep for them. Maybe that's how she really felt about you and you in turn messed up. I can't blame her-I don't like liars either cause if you lie once it just makes it that much easier to do it again and again. Hopefully you've learned a valuable lesson in life and won't repeat it.

It's called trust dude and you broke it.

You have to give her sometime and then face her face to face. No begging. I apologize out right. SINCERELY.

You did not say what you did... so I can't completely help. Did you cheat??

You're the one who screwed up. You have to pay the piper.

Tell us what you this and we could help further.

BUT. Leave this girl alone for a long time. She needs her space if you lied. You do need to apologize face to face.

Lying to woman is about the same thing as shooting her dog. The trust is broken. Not good.

Just move on man, there are plenty others out there.

Its better to ride solo anyway :D
