Maybe its not so much bad feelings as it is a lack of good feelings.
Bitterness, anger, apathy. Mostly, I'm just tired all of the damn time. I exercise most every day, but I never feel good. I feel unproductive. Obsessive thoughts, etc...
Physicality isn't wearing ya down. It's your emotions wearing ya down. You can exercise the **** out yourself, but doesn't mean jack with the other negative emotions ruuling your body.
It's a perception thing. Using emotional reasoning and prolly some other cognitive distortions to validate the feelings. Man, dude, i lost everything brother. I sit here alone most of the time. Yeah, got a part time hot girlfriend, but she can be weird. What I'm saying 93, it's all perception. I feel depressed a lot. Try not to, but it's tough. I think you know the reason why you're having ruminating thoughts. Go to the core of the issues. Compartmentalize them separately, rather than sticking them all together which can seem overwhelming.
