mmm Chado... maybe I don't know what I'm getting into... and maybe you don't even have enough energy to read to the end of this but...
I second what everyone says about exercise. Are you exercising? And by exercising I mean just normal movement. Like walking around like shopping or something. Like in the ancient times where you have to at least move around a bit for the better part of the day for a living. Like gardening. Doesn't have to be lifting weights or put on your shorts to go running. Can just be walking around the neighborhood.
Not having a minimal amount of movement will keep you depressed even if you have the happiest thoughts in the world.
I know I'm not clinically depressed, though I have natural states of being blue and lazy as heck just as everyone else does. And I've found that is always some combination of these things:
-Not drinking enough water.
-Forget to eat breakfast, and then eat a good meal to fill me up... for the next hours or so I'm just totally knocked out. The energy it takes to digest the food sucks out all the energy away from my brain so it makes me temporarily blue/depressed
Not moving.
Another post about minimal movement
Not having variety.
Having too much sleep.
Apparently over 8 hours is correlated with a higher mortality rate.
Yes, letting my thoughts go loose and having too many negative thoughts.
Being lonely. I know you used to be in love with your ex girlfriend... man this might seem nuts, but I'd
learn how to pickup women. Why? Because you would have to be moving about, you'd have a strong goal of learning how to find someone you can love again...
the subjective feeling of being close to people boost your immune system and gives you a cognitive boost, being lonely kills it...(from personal experience) you'd get minimal amount of movement depending on the places you go to.
But you can have immediate relief from being lonely... this will seem absolutely nuts, but it physically helps me concentrate better after I've look at some picture of cute faces for about 10-20 minutes... Like I might be frustrated about something and things just seem horrible. I first have to realize that I'm in that state and then I look through these pictures of my cute friends. At first it doesn't seem like it does anything to me. But then stick with it for 10 minutes and it calms you down. And it gives your mind a chance to focus its thoughts so that you can plan things out and move forward. It me gives a cognitive boost. It lowers my anxiety. I feel silly for sharing this, but here's
my collection of pretty faces that helps me out (i'm not in any of those). I have so many just for variety...
What I typically do is when I found myself stressed out and feeling bad and like crap, then I look at those picture for 20 minutes. It makes me feel better, less lonely and during that time I imagine myself getting up and going outside. Then I have energy to just go outside and walk around. While I'm walking around then I'm able to focus and get motivation to do other things and escape my black hole room and avoid becoming blue from purely physical effects.
But anyway its a combination of all those factors... positive thinking is one of those factors, but if the other ones are off, like not getting enough basic movement and being lonely, then it will cause you to have negative thoughts and makes it harder to have positive ones.
And no I'm not a doctor of course... all this from my personal experience...
