love n life

hi i m sarmistha...m a single.but i do doubt that how people say that they are happily single or happily commited...?????? i hv seen rather had experience that whn 1 is single one feels lonely whn his/her frnds r engaged...... we feel jealous whn we see them happily together........but whn they fight n heart breaks then we thank God that we r single.....well its confusing..........
