The grief can be overwhelming. Find a quiet place, and let it out. Crying is really, really good for you.
No matter how much you’re hurting, it doesn’t mean you have to DO anything. As humans, when we are uncomfortable, scared and hurting - we try to fix it ASAP. But that doesn’t work with a broken marriage. There’s nothing you can do, say, be, promise or force that will make it better. You’re better off acknowledging your grief, embracing it, and understanding it is actually your pathway to healing.
As much as your entire world and everything you knew has been turned upside down, the world will keep turning. You’ll be okay one day. Maybe not tomorrow, maybe not in a few months, maybe not in a year. But one day, you’ll be okay. And happy and content. The majority of us that have been through it actually end up being grateful it happened.
Do some reading about mindfulness. It’s essentially reconnecting yourself with the here and now, dropping expectations and timelines and pressures - bringing yourself back to neutral and becoming aware (almost like stepping outside your own body and looking back at yourself) of your breathing, heart rate, emotions and cognitive patterns.
Google Jon Kabat Zinn YouTube mindfulness, and try it.
And exercise, exercise, EXERCISE! It’s the BEST thing you can do for your mental health. Better than counselling or anti-depressants.
Started back running, 32 degrees when I ran this morning and I loved it. Just me, my music, and nature. No thinking, just running. So helpful, gives my mind a break.
