In the moment, grounding techniques help. I describe what's around me or do the 5-4-3-2-1 method.
A good therapist can help. Support from family and friends. A good supportive midwife. Try and breath, 6 seconds inhale, 8 seconds exhale. Maybe try to write some things down. I hope you find some inner peace xx
For me personally it was walking and going out for fresh air, although I have a feeling you will have already tried that. It helped me that I have a supportive partner that I can turn to for anything, I hope you have the same. Don’t ever suffer in silence reach out. All the best, it will be okay 💕
