When you cannot function: perimenopause and staying in bed

All I want to do is stay in bed and I have to force myself to get up. You are describing something so common it has a nickname in the forums: bed rot.

It is not laziness. Falling and swinging estrogen genuinely changes how your body regulates energy. You are running on a broken fuel gauge, so everything costs double.

Start absurdly small: one thing, five minutes, before you decide anything else about the day. Then log how tomorrow compares. A pattern usually shows up within a week or two, and that pattern is what gets you taken seriously when you ask for help.
