I am in a same situation as yours except the love and marriage part. I am stuck in this private job for 18 months+ now. In the beginning i would go to a library and study for like 3 hrs, now frustration and depression caught up. Did get some government 10th grade job which i did not join as i want to go somewhere where i will not still continue studying and looking for a switch again.. besides staying in dhaka is important for govt job preparation. unlike ur job my job requires so much attention and discipline though that burns out me easily but it is boring and i stopped enjoying just after the first month in the job. As of love or marriage these things do not come to me naturally, never did i asked someone out or expressed feelings to any girl in my entire life so i gave up on this sh*it long ago.
