PS. I miss mine too. But I know she was unhealthy for me so I have to be strong. I wrote a list of reasons why she was bad/ways she hurt me/painful things she said, and I keep it on my phone and read it everytime I get the urge to contact her. Maybe you could try something like that? I actually got the idea from the "acting opposite" DBT handout. It was about "acting opposite" for undeserved love, but I think it works too for just questionable yearning in general. At least it will help you see where you are. If you can't come up with a lot of reasons not to contact her, maybe you could give her another chance.
