have u ever been dreaming of someone u wished u had a life with
but it didnt happen or maybewaiting to happen. But when u
look at their facebook, blog or hear about them being happy, doing
well in career or studies ( what they are currently doing but
not necessarily attached to someone else) from frens, u feel
jealous and u feel down about yrself?
why is this happening? 
Hi ☃®,
As A.T.R. has kindly pointed out, the reason why one will feel
jealous and down in such a case is mostly due to a sense of
inferiority. Instead of comparing with others, regardless of
whether you are interested in them or not, you can try having a
look at your own strengths and positives instead.
On a side note, being jealous of someone whom you like is not
exactly a healthy mindset - You should be happy that he/she is
doing very well right now.
Cheers.
