craque sprung 🏳️🌈<p>Pushing core workout lately and being rewarded with more mornings free of migraine.</p><p>I played deeply into my music the past few nights, awaking the next morning scrubbed of a migraine.</p><p>Having those who listen and witness allows me to let go of emotions when I am having them, not carry them around. Less migraine activity ensues.</p><p>This week I learned that my anxiety about others is entwined with a particularly evil symptom of religious trauma, I saw both but never saw hiw they were connected.</p><p>I can recognize it now. And the feeling of not needing to "save" someone is a really powerful emotion - or lack of one - that, today, I am thankful for contributing to a clear head and no migraine.</p><p>Also feeling self-assured that fixing failures in our systems look a lot more like treating a migraine than using quick-fixes and low-hanging-fruit.</p><p><a href="https://c.im/tags/migraine" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>migraine</span></a> <a href="https://c.im/tags/CPTSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CPTSD</span></a> <a href="https://c.im/tags/recovery" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>recovery</span></a> <a href="https://c.im/tags/SRE" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SRE</span></a></p>
