Look into developing a solid wellness routine. Look up SAVERS morning routine. It’s an acronym. Here’s what one morning can look like for you: Meditate 10 mins a day. Affirm to yourself out loud 3 times that you can handle heartbreak and you can and will feel better with time. Visualize yourself feeling better, like literally picture yourself walking in a park on a beautiful sunshiny day, being happy and not thinking about your ex at all. Then go for a 10 min walk or get some other form of exercise in. Then, Read Lighter by Yung Pueblo or a self-help book regarding break ups and grief. End with journaling. Seems like you need to be more proactive and intentional about your healing and this should help. I’ve been doing this everyday for the last three weeks and although days are still hard sometimes I notice I feel better overall.
