My prayers are with you. Breath now. Focus on your breathing for a while. Our breath is our spirit. Let it draw you to a place of calm. Stay in the moment with your breath. Acknowledge other thoughts trying to pull you away but return to your breath. Stay with your breath as long as you can. Acknowledging other thoughts and feelings but always coming back to your breath.

That exercise helps pull me out of many those pit dives you describe. Don't try to make it right. Making it through is all you want to deal with right now. Getting some rest from your pain is what you want to achieve right now. Breathing can provide you a focus for meditation. It's even more effective for me if combined with nature. Sitting in the forest, walking along the river, gazing at the stars, holding a rock can become a source of mediation and a channel of strength.

Detach yourself from the negative thoughts and feelings by focusing on something that takes no effort to appreciate. Earth, wind, fire and water...... channelling God's love and power to you.

Blessings.
