You are in the same boat as me.. however.. the problem is because you are alone. Try to surround yourself with friends..find a way to come back home. It will help you. I wonder too at times whether taking my life is REALLY the solution, however it is not. No one is better than your ownself. Like you said yourself, you are financially independent..you dont need anyone to take control or be with you all the time, try to socialize more..there are more to life than just one guy.. and ..

P/S : I am a guy.

Parents always do worry about their kids, that is for sure. But at this stage of your life, you and ONLY YOU are in control of your own life, you can help them by moving on indefinitely, and speaking from my own experience, I surrounded myself with colleagues and occupied myself with work. Trying not to think about it. You sound like a very independent person, occasionally you can tell friends and colleagues about your issues, however over-telling your story might bore them since they and you BOTH know the solution. TIME will HEAL, some will take months, some will take years, but my advice is, taking your life is not the answer. Companions do really come and go, even friends, that is just part of life, life is tough some say, be strong. You always have lowyat here.
