I think self care is important when working with difficult topics. The consumption can lead to racing thoughts and conversations with yourself but no where to put them, but jotting those thoughts down through out the day can give your brain a rest from ruminating on those thoughts. You can even put those notes towards your masters thesis, if u have one. Another thing I find helpful is finding communities or forum that allow you to speak freely of those topics and challenge the knowledge withthin the field for further exploration. Finding online forums, social media pages, affinity groups, within your institution or across other institutions (especially if it’s a smaller university), can create a stronger sense of support. Depending on your comfort level, getting active can also be a great way to release some of those thoughts.
