I stumbled back onto this post as I was looking through old threads. It made me feel happy, as I remembered how sad and depressed I was at this time, and how difficult it was for me to get over it.
I do still occasionally think about my old friend, but I'm so much better now than I was. The group of friends we shared I have moved on from, and found much better ones. I have a new best friend, who is amazing and we get along so well. Without her I don't know where I would be.
Although things happen which can put me down, I feel overall very lucky to have found this new person and new friends.
