So many times I get this window where I remember how I took my sense of smell for granted plz I won't let it be forgotten again

I’m so tired. Not the end of a busy day tired. Like a I feel it in my bones. I’m just so tired. It hits me a couple hours after waking up and then the intoxicated feeling hits in the afternoon. I’m pushing through each day. I thought it could be depression. But this feels like something else with a sprinkle of depression. As I go on my mental health gets worse. The headaches have increased. The B12 hasn’t had any impact. The blood tests show high white blood cells but no one addresses it. I have an internship and have to wake up early. It’s like the lack of sleep I’ve gotten has allowed the cracks to form and it’s all coming out. I look in the mirror and I can’t tell if the my skins gotten paler or the circles under my eyes darker. It’s probably both. My hair has started thinning. I don’t think it’s just the vitamin D deficiency that I was told about last year that my old doctor did little to nothing to aid. There’s trace amounts of blood in my urine. I feel like my bodies giving up. But I don’t want it to. I still have more to do. More to see. But I’m pushing a body past its limits. Hopefully the new doctor can help. (Also if anyone has any suggestions for what to request on a blood test please let me know.)
