You need to work out what triggers these feelings ? These 'other people' are they close friends, family, colleagues ? What is your 'status' - as in do you own your own home, or live in a flat ? Do you drive and/or own a car ? Is it because these people have things that you would like / or unable to afford ? I have a friend who gets like this - he has just gone bankrupt, rents, cant drive, BUT has a job (which he is thankful for!), however every penny he earns is accounted for....and he does get very down about it....perhaps Im not explaining this very well...alot of people do live beyond their means these days...more often than not....
