I feel like I'm stuck in the past. I can't seem to shake it.
Do these thoughts bother you at specific times?
Most often when I sit to eat with my family.
It's easier said than done, but gotta stay focused on the present. That's the only thing there is: the present. No other moment matters.
Do you think that my family can feel it?
They can probably sense that your attention is elsewhere. It's okay to occasionally feel nostalgic, you gotta stay focused.
