Whether or not magick can help you, in this case it is my firm belief that it should not. You cant just cast a spell every time you have to talk to them. Some life skills you just need to develop.
I am new to the site. But, I feel the urge to intervene here. At your age, I believe with all my being that the best way to handle this situation is for you to talk with these friends that you are having problems with. Learn to use your communication skills, not magick.
I'm not saying the magick won't work. I just believe you need to put yourself out there and really communicate with the girls in question. You can't rely on magick to all the 'dirty' work for you. You must learn to handle some issues on your own.
Oh trust me I tried just to talk but it didn't work. I always first try non magickal solutions. Unfortunately it didn' work. I tried a few times, a few ways, it didn't work. :S So the talk didn't help :)
Have you tried giving these girls some time? Maybe the reason they won't talk to you is that they are upset right now and need some time to think things over. What I would do is instead of hounding them, sorry if this comes across rudely; leave them alone for a while and give them a chance to sort things out. They may come back to you, they may not. After another month or so, when you can see they have calmed down try to talk to them then. Don't respond to any threats or rudeness, just make it clear that they're your best friends and you still care about them very much. Don't try and guilt them into anything, just let them know how much the fight upset you but; also try and focus on them and how they feel. Try to listen to their side of the story if they will talk to you and figure out what you did to upset them. Once they tell you that ask them how you can fix it. There is no one hundred percent guarantee that it will work and try to stay away from magic on this situation. Think about this, say you did get your friends back and they somehow found out that you had been using spells to manipulate them. Assuming they found out, they might feel betrayed and it might turn into an even bigger fight then you are in now. I'm not here to lecture you, I'm just here to give you some advice so; you don't have to listen to anything I say or take my advice but, I'm sure giving them some time,trying to understand them, and seeing where you are at fault would help.
