Depression...

• Things just seem “off” or “wrong.”
• You don’t feel hopeful or happy about anything in your life.
• You’re crying a lot for no apparent reason, either at nothing, or something that normally would be insignificant.
• You feel like you’re moving (and thinking) in slow motion.
• Getting up in the morning requires a lot of effort.
• Carrying on a normal conversation is a struggle. You can’t seem to express yourself.
• You’re having trouble making simple decisions.
• Your friends and family really irritate you.
• You’re not sure if you still love your spouse/significant other.
• Smiling feels stiff and awkward. It’s like your smiling muscles are frozen.
• It seems like there’s a glass wall between you and the rest of the world.
• You’re forgetful, and it’s very difficult to concentrate on anything.
• You’re anxious and worried a lot.
• Everything seems hopeless.
• You feel like you can’t do anything right.
• You have recurring thoughts of death and/or suicidal impulses. Suicide seems like a welcome relief.
• You have a feeling of impending doom - you think something bad is going to happen, although you may not be sure what, and/or...
• ...You have a very specific fear that torments you constantly.
• In your perception of the world around you, it’s always cloudy. Even on sunny days, it seems cloudy and gray.
• You feel as though you’re drowning or suffocating.
• You’re agitated, jumpy and and anxious much of the time.
• Your senses seem dulled; food tastes bland and uninteresting, music doesn’t seem to affect you, you don’t bother smelling flowers anymore.
• Incessantly and uncontrollably into your mind comes the memory of every failure, every bad or uncomfortable experience, interview or date, like a torrent of negativity.

Finally, I got to understand the reason why I'm having unexplainable feelings...
