Mercury will help with communication. Emotions shouldn’t be ignored, that’s not a healthy habit. Rather, one should learn mindfulness skills, to allow the emotions to exist in your body, observing them, knowing you are not your emotions. They will come and go, passing like clouds, and you are the clear blue sky.
Field: Unbreakable. To stay strong.
Please look into getting support or professional counseling or therapy, if you and your partner aren’t already. I am partial to ACT (Acceptance and Commitment Therapy), but for BPD, DBT (Dialectical Behavior Therapy) might be more suitable.
I know these services are not always accessible to everyone, especially in these times, but there are some resources online. The Emotional Support field as mentioned is a start, and you can use that alongside learning healthy emotional management skills. I like the Therapy in a Nutshell channel.
Just know that this is something you shouldn’t feel like you have to handle all by yourself.
All the best.
