What is this feeling ahaha

So for a while i have been experiencing depression and anxiety, but tonight for the first time in a while i have been able to complete a task without having to stop due to overthinking or not having the energy to do it. Like i don’t feel sad or stressed but i also don’t feel happy.. Like my mind is blank for the first time in so long and i like it, but just wondering what the hell i am feeling in terms of emotions ?
