Well, suicide or killing ppl doesn't solve anything, it just brings more pain to people around you, or us on this forum who would miss you... Life can still bring soo many beautiful things, even if at times it may not seem so... (Personal experience!! of things changing, even unexpectedly!!)
SweetCupcake, I can relate to some of the frustration and remember what it was like when I was younger... Trust me, not all those 'happy couples' survive many happy years together... Some do, some are freshly divorced by the time you'll be maybe happily in love with someone who you took time to get to know and might be with for a long long time?
Some of my friends met their boyfriends after 24 and they are soo happily married or partnered up... Some people meet significant others after 30 too, and have happy lives together... Yup, some have kids too...
It's good to be proactive and have eyes open, there are many books or articles you can read to help you with the art of flirting or communicating etc.
As for envy, intereasting thread... Yup, I have envied people too, some of them on this forum, or elsewhere... Some people are just soo beautiful, and talented, and 'not-undecided' and seem to 'have a clue' or 'have it all figured out' and have families and careers etc. There are always people who are more 'something' than we are, and others who might envy us... So maybe it helps to look at oneself 'in the middle', learning things, evolving...
Learning to communicate effectively in a wide range of topics and situations and be at ease with people is part of personal growth...
No baby is born like that, communication and a healthy way of thinking is something we learn...
