I know how you feel completely, lala-land123. I have had this recently as well and have been thinking about past memories in all negative fashions rather than anything positive. Time moves so quick that it is difficult to comprehend where or what you are doing right sometimes. Just know that time anxiety (chronophobia) will put a damper on the present and future. This is easier said than done for me as well. My girlfriend tells me I have FOMO (Fear of Missing Out), which makes me severely anxious with any choice and activity when I can be doing something else. Time comes and goes, just try to enjoy every moment you can, even if that is difficult. Feel better
