Sometimes I get this feeling like there's fog in my head, a blurring of consciousness, accompanied by general weakness and a lack of desire to do anything. Sometimes I try to alleviate this unpleasant state with sleep, but when I wake up, the condition returns within 15 minutes. To say that I'm going crazy is an exaggeration, but the sensations are similar. My head feels mushy, bad, and there's a vacuum inside it. Has anyone experienced something similar? Who can I turn to for help with this? It happens when I'm alone. When my husband is home, he distracts me. But he's at work 80% of the time; he's a doctor, you know
