How do I let myself rest on medical leave without guilt?

You did the wise and difficult thing: you took the leave you needed and arranged it so your job and income are protected while you heal. That took courage, because so many people push through until they break. The guilt you may feel about resting is worth naming, because it can quietly undo the very healing the leave is for. Try to see rest not as doing nothing but as the actual work of this season. Your one job right now is to recover, and every day you let yourself heal properly is a day you are protecting your future ability to work, to show up, to be there for the people who count on you. Guilt tells you that you are shirking; the truth is you are investing. A body and mind given real time to mend come back stronger than ones dragged along broken. Trust the choice you made when you were thinking clearly. You would not begrudge a friend this same care, so do not begrudge it in yourself. The work will be there when you return, and you will meet it better for having actually healed. Let the leave do what you set it up to do. Rest is not the interruption of your responsible life. Right now, it is your responsible life.
