I'm stuck in the past and have no motivation to change anything
What about the past keeps you motivated to stay there?
I think it calms my worries about the future.
It's understandable that the past makes you feel safe. However, you should try to live in the present moment so that you do not let your life past you by. If you stay in the past, you will one day regret all of the opportunities that you missed.
I don't care cause it doesn't make any difference.
But it does make a difference. Life stops for no one you need to be able to adapt and overcome.
