We all get depressed from time to time, sometimes for very tangible reasons & at other times, it just happens. There is a big difference between, I feel bummed out, I'm bored, No one likes me, my girlfriend dumped me to, I don't want to live, why go on living, life sucks why try. We've all been depressed, bummed out for 1 reason or another but over time the sky clears & you hop back in the saddle again. The best thing is to let yourself feel sad, mad, glad, it's normal, get it out of your system, we all blow off steam in 1 way or another. Depression in the clinical aspect is more recognizable to those that know you, & your behavior patterns. Quite often someone in clinical depression won't, can't, or sees no reason to get out of bed, to socialize, work, play, breathe you name it. Normally it is something that treatment and/ or medicine is the answer. So if you're bumming out, it's okay, give it a little time, get together with some friends & raise heck. If you're really down, talk to someone you trust
Talk with someone you trust in hopes they will show you a different way to look at your situation. You can also try to think about all those that are less fortunate. It can make you appreciate the way you live or who you are. The right attitude can bring happiness to anyone regardless of their situation. Just a thought. All the best.
Speak to your doctor first. I'm speaking here from experience: I have dealt with recurrent, cyclical depression, off and on, for most of my life. BUT! You do not have to suffer from it--depression can be treated, with therapy, or with medication, or both. About twenty years ago, with the help of my doctor, I found both the right medication, and the right therapist, and have been in remission ever since. Notice that I say "remission"--I'm not "cured", and as with many mental illnesses, I likely never will. But that's OK--i can live with that medication, and I mean just that: with that, I can live, instead of going around thinking about finding a way to kill myself that wouldn't hurt my loved ones (hint: that's impossible), as I used to do. Now, it's true, I have essential depression, the kind caused by a chemical imbalance in the brain. You may be suffering from situational depression, the kind caused by some occurrence (the injury, or even death, of a loved one, the loss of something valuable to you, having an injury or illness), which is, after all, self-limiting. But depression is not like a cold, and wishing it away may not work. So, if it's taking the joy out of your life, and doesn't seem to be going away, it's time to call the doctor.
When Im feeling depressed, I usually like talking to someone I trust and explaining whats bothering me, and hearing nice jokes and hanging out with friends, or I just put my headphones in, blast some music, and block out everything. It helps ease the pain.
Usually if I wait a day or so it goes away . In the mean time besides getting some extra rest which helps , I tackle a task that I've neglected. That does 2 things 1) it takes your mind off being depressed & 2) it makes you feel better to have accomplished something.
