Well now the anemia dx makes more sense. Because I'm having all the symptoms. Symptoms that can occur include extreme tiredness, weakness and shortness of breath. People may experience: Whole body: dizziness, fatigue, lightheadedness, or malaise Heart: fast heart rate or palpitations Also common: brittle nails, headache, pallor, shortness of breath, or weakness Maybe that’s where low CO2 is from. Idk. Anyways, I'd go outside more but for the allergies, memory issues, and fatigue. Plus I feel like i have indoors work to do. Buti think today, the weather is nice so I'll sit outside.
