Is it possible to be fully happy?

Tweet

To be quite honest right now i have a pleasant and enjoyable life with a stable relationship, a loving family and no financial problems whatsoever, and i suppose i should be happy. However somehow i am constantly afraid of losing most of the things meaningful to me, because i see people who suffer day by day and i am questioning myself why do i deserve these things and they don't? I strongly believe in equality and kharma and i do not believe that i am truly deserving of what i have or that people who can not enjoy the same standard of living are in any way less deserving that i am. I am not trying to be ungrateful for what i have and i do try to help those in need, i simply wish to understand this constant nagging thought.
