Brain radiation after surgery not WBR

Hi there I’m finding it hard to get experiences of side effects of targeted radiation to where a my tumour was after surgery. 3 weeks ago I had a 2.7cm tumour and margin removed from the cerebellum part of my brain and I am to have 10 sessions of radiotherapy at 1-2 minutes duration each. As it’s only 10 sessions and now whole brain radiotherapy I was wondering how bad side effects and tiredness are usually? Will they be milder for only 10 sessions? And because it’s only part of the brain? I can only find experiences about wbr or targeted radiotherapy that goes on for weeks. I would be most grateful and send positive thoughts and supportive hugs to all us brain mets peeps x
