At age of 28, you should look at your life in a bigger picture. Instead of spending so much time on work, spend more time on your family and yourself.
Also, I want to add that the feeling of being a loser is exactly because you are not thinking about your life holistically. If you are really depressed, and feeling this way all the time, you need to talk to a mental health professional.
What you are feeling is normal. Take a look at the book Why we do What we do: Understanding Self-Motivation by Edward Deci for some insights. Relentlessly work on improving yourself to get "better" at various aspects of "Programming" (assuming that is what you want). Don't compare yourself to others, focus on incremental improvement everyday and set your own Goals/Criteria. Become Self-Driven and proceed at your own pace.

but if it helps you ....
Nope.
There is a reason i mentioned Deci's book; i highly recommend going through it. Peak: Secrets from the New Science of Expertise by Anders Ericsson is also relevant here.
