How can I go so long feeling completely happy, then suddenly my depression knocks that all down?

From my experience, I feel like depression never truly leaves you. Even if you have worked through it, those thoughts and negative tendencies are there. So even if you are feeling happy for a long time, if you are not taking care of yourself properly, your depressive thoughts may sneak back in there and take over when you least expect it. From what I have dealt with, the feeling of depression can increase and decrease, but it is harder to actually change the ways that you think.

it is easier to b depressed then it is to b happy it take effort to b happy it take no effort to b depressed

Depression is a bully. It's a coward that hides and then comes back when you least expect it. Depression gives you time to be happy and then steals it away from you just because it has that power.

Depression is not something that goes away- even if you take medication or have been feeling 'good' for some time, it is a condition that needs to be managed, like any other. It's very difficult, in my opinion, to ever call a mental condition 'cured' - but what we can do is take care of ourselves. What you need in order to take care of yourself varies wildly depending on your particular condition. It may be that you are a person whose depression requires medication- in which case, you should make sure that you are always taking your medication responsibly and checking in with your doctor(s) to adjust the dosage if necessary. It may also be that you are a person who needs to learn to manage your depression in more proactive ways, such as seeking therapy, learning cognitive behavioral coping skills, or something of that nature. If medication alone is not enough (and in my experience, it's usually not), then I think it's very empowering to learn to take charge of how you manage your own emotions. The bottom line, though, is that you should never feel like the depression is something to be completely helpless about- these feelings are a symptom of a disorder that you have. They do not have to control your life.

Depression is tricky. It disappears for such long lengths, and when you think it's finally gone for good, it creeps back in. I'm not sure exactly why it happens that way, but it happens to me as well. I just always remind myself, hey, it'll go away soon enough and you'll be okay again. You'll always be okay.

Sometimes everything is off your mind and that's good. Try think happy things, like pets or something you are looking forwards to.

Well without some sad bits happiness really doesn't have that flavor. But how about you try to find out what causes this depression and try to resolve the roots of the issue? Once you do that maybe you might find yourself on that happiness streak forever.

Through my personal experiences i recognized that depression is silent and can lay dormant in yourself for a long time before you feel the effect. I suffered an immediate accident that hurt me both physically and emotionally. It took me months before i began to suffer PTSD and depression, it hit me suddenly but i still manage it on occasion. Time is healing, but only if you take your own steps towards helping yourself.

Depression can kick in at different times, most of the time it can be triggered by a thought, object, place, or just something related to a sad time in the past. Being happy is great but life isn't all rainbows and sunshine and depression helps you realize that. Of course don't be depressed all the time, but try and balance your emotions and express them at the right times. If you keep your emotions in, it might affect your mental health.

The funny thing about life is that we are always more acutely aware of pain than we are of any other feeling in our world. Our bodies can be 100% fine for years, then we get a toothache or a broken bone. We are more likely to remember that toothache or that broken bone that lasted just a short while (a couple days, to a couple months) far more intensely than we remember all that time when we were just fine. This happens BECAUSE pain, either physical or emotional, is a flag sign to our body that something is going wrong, something isn't working the way it should, something is injured. Our brains process this flag sign and consequently begins to worry over/have anxiety of how to fix the injury. This is a natural response and it is what happens when we face depression. We get an injury emotionally that our mind wants to fix; so we forget all the happiness we had, while we puzzle out how to heal our current distress.
