Being alone with your thoughts is uncomfortable at first, like a new gym. Keep showing up.

The discomfort comes from unfamiliarity rather than from anything being wrong with you. Your attention has been continuously occupied for years, so the first quiet stretches feel loud, restless and faintly unpleasant. That eases with repetition, the way anything unpracticed does.

Keep the sessions short and regular rather than long and rare. Ten minutes, most days, with nothing to do in them. Expect the first week to feel pointless, and judge the whole thing after a month instead.
