Taking time out from anything that overwhelms you is a good practice for mental health. Whether this be work, studies, a toxic relationship or tasks you have set yourself at home. When it gets too much, it is a good idea to step away for a while and reevaluate why you need/want to get the tasks done/be in that relationship. If, after re-evaluation you are not able to/ do not feel up to doing the tasks/ be in the relationship talk to someone who can help – with reducing the tasks-finding a way to do them quicker/get away from the relationship.
There is always a solution.
