Depression or Regret

It is a common hearing we hear from our surroundings..., I am depressed.. My question is to a believer, that How do you know that u r depressed.?.. No, Actually we r not depressed.. It is just the thinking of our own mind... A constant hearing from surroundings... Depression, Stress, and many more........ I will say depression is nothing else.. Instead it is Regret...any type of regret... Regret of being egotistical, being stubborn, being lazy, being late.... And then instead of learning a lesson and doing work.. We get involved in thinking that moments and that moment again becomes a Regret... BUT u know A believer never get depressed... Because he knows where he has to learn a lesson from the past and how to incorporate that pressure (which causes depression) in his work.. .... Never let your regret to become your depression..Be a Spark of Hope.. #Viking
