Worrying, stressing and feeling negative, are active processes of your mind, and that requires energy. When your mind is distracted by something or tired in certain ways, it can ignore some processes in some areas.
Someone who meditates properly has no cares at that moment because what they're doing when meditating is letting all of the mind's focus come at one point, and some people are able to maintain that state of mind almost constantly.. so it's technically possible to be ok with anything, even gid, when you have the right state of mind.. unfortunately, most of us aren't monks, and in your case, it seems like your mind is merely distracted by your other concerns and depression.. or tired of worrying about it for now.. so, I guess you just have to experience more and try to understand your mind better to determine what's what. Don't rush anything.. live and learn.
