I think it's great that you have the maturity to understand the importance of speaking things through and sorting misunderstandings like an adult.
You've put up four posts asking for help. This goes to show how much you want this to happen. And when you want something to happen this badly, it does. The magic you should be tapping into is positive thought and faith in your desire to deliver. Dont let your fears and apprehensions get in the way. Because the only things standing between you and your friends are your own negative thoughts and fears. Be positive and I wish with all my heart that things work out for you.
If you believe in angels, then Archangel Raguel, healer of strained relationships, is someone you can turn to for a little help. If I were you I'd light a light pink candle, write a letter to the Archangel and read it out as many times as possible. Then I would turn that letter into spirit by burning it in the candle flame. I would thank Archangel Raguel for helping me. I would also gather the ashes of that letter and sprinkle it in a flower pot with roses or any other flower. I would pluck three of these roses, one for each friend, and present it to them along with a box of chocolates, as a symbol of my desire to be friends with them again.
There are two things that are likely to happen if you choose to do the above
1. Archangel Raguel will intervene and remove all blocks between you and your friends.
2. Archangel Raguel will not intervene because the reason these three friends had to play in your life is over and all four of you need to go your own way.
But whatever will happen, will happen for the best.
Positive energy be with you :)
