Hi Venny,
Maybe take a deep breath and give yourself the freedom to change your mind and get back with her. (atleast just in your head) Sometimes because we tell ourselves we "shouldn't" we get caught up in feeling like we "can't" which makes us crazy. Give yourself a minute to think about getting back in contact with her and play out what has happened in the past when you do that. Feel the confusion, the hurt, the pain, all your thoughts in your head spinning... .
Then decide, just for today, that you don't want that. Each morning, wake up and think about it and decide just for today, I'm not going to get in contact with her. Hopefully that helps slow you down until you can get balanced again.
This is AMAZING advice! I've saved this for myself, thank you x
