If your mention of suicide was a genuine thought, and not just a "hey my life sucks, what's the point", then you must seek help immediately. Severe clinical depression is very serious and cannot be handled alone. You need to see a doctor who understands this kind of thing and won't just shrug it off and tell you to pull yourself together. If you aren't satisfied with one doctor, move on to another, and another until you find one who will take you seriously and refer you for the help you need. Yeah, "shit happens" and "there are millions out there worse than you are", but if you are truly clinically depressed then you are not handling things and it doesn't matter what the reason is, if it's less or more serious than others... or even if there isn't really an apparent reason for your reaction and feelings. Depression doesn't always have a reason, or it can be a suppressed reason that you aren't consciously aware of. Often it is a chemical imbalance, possibly coupled with a life experience. Quite likely you need medication and therapy... certainly an assessment and ongoing monitoring. So please, seek help. Don't delay. We don't want a tragedy. And neither would your loved ones. So, for their sake and yours, be proactive and get the help you need.
You are a strong and powerful man! Life is a precious gift from God. Put a smile on your face, open your heart and your mind and you'll see the solution to your problem...Love is the key to all. Keep the faith and everything will be great for you!!!
If you are feeling that bad, please see a doctor or seek some form of help. Putting a post like this on a webmaster forum may attract some less than sympathetic post that will only add to you feeling bad as you read them.... Your mood can be lifted, be honest with yourself about what is making you feel so bad and remember - anything can be changed. Hope you seek help and feel better soon
