I have been suffering from problem of comparison and regret of past . When I was in 10 I worked very hard but comparison with others I ruined and in this regret I ruined my 11 . This is not being stopped and also my B.tech is ruined in the regret of past mistakes and this is on . If I prepare for any competition then I start to compare myself with others and this create lot of pressure in me and when I come out of this problem then I start to regret both creates lot of pressure in me . Help
