How to have a 'me time'?

Hello mommies, can you share how to have a 'me time' with a 6month old baby? Formula fed si baby kaya ung ibang time, nagagamit sa cleaning and preparation ng milk/food ni baby. Mejo nadedepress lang po kasi ako, and pakiramdam ko po na its unfair although I truly accept motherhood. I just want to breathe in breathe out. Masyado ko po sinisisi ung sarili ko sa mga bagayy bagay and been overthinking a lot. To those who encountered being like this, please share or help me to overcome this unwanted thoughts. Your recommendations and comments are highly appreciated😇😊
