I found away to do meditation one minute at a time. It's not that you do not have patience, you body is still telling you that you are in fight or flight mode. Start with 1 minute and tell yourself you have done well to start. When you feel ready try for 1 minute 30 seconds or 2 minutes. Again tell yourself you are doing well. There is no judgement. I find if I put myself in a quiet room I do better. Somedays it just a minute, other days it's 20 minutes and I might even fall asleep. You are enough.
