Alright so here is my experience:
When I got married and had to leave yeshiva/kollel very soon after (since no one was supporting us) I soon fell into a deep depression. I felt that all my lifes goals were ruined. And that depression probably lasted over a year and did serious damage to my marriage/yidishkeit/life in general. Now I don’t feel saddened and worthless because im not learning full time. I used to though. I think it was because I used to think a life of full time learning was the only way to be a good jew. I thought i was a failure for working. Now I know that isn’t true thank G-d.
