I've been feeling a lot since recently. One thing about me, I'm always gonna say I'm okay when in reality, I'm struggling. I've been learning to accept when I am feeling something like sadness. I'm learning to accept when I don't feel okay. I do have a habit of allowing my mood to ruin my day but I'm trying to control that. It's okay to have a moment of sadness but don't dwell on what happened. It's human to do that but this is what causing overthinking. It normal to think about what happens but overthinking causes you to think of situations, normally negative, of what happened and it just makes your mood worst. Things aren't meant to change overnight but taking the steps to be better is a start.
