The worst part about that exhaustion is that my parents always says "when we were your age we'd go back from work and do everything at home that needs to be done, sleep less etc" but they don't understand that I'm more psychologically tired than physically and that prevents me from sometimes even doing these basic chores. In my first job I was only dealing with graphic design for one art centre and I was in contact with only one person. Now when I have my own business and clients literally come from the street (I still do graphic design, printing stuff, photography (for ID, visas etc), old photo restoration and stuff like that) and I'm mostly tired of interactions with other people who are very demanding with getting stuff done preferably by hand. That's very stressful cause I do various multiple tasks everyday and sometimes I'm just not able to do everything till deadline (so I stay after working hours very often, I simply don't know when a big project will come up and it has to be done for a sole reason of earning ever needed money).
About constantly thinking about comics: it's not that I think about it every minute, I tend to think about it while doing tasks which don't involve my thinking process too much, like cleaning, vacuuming, lying in bed while I can't sleep, brushing teeth etc. At first it may seem forced but in no time you'll just start thinking about your comic like about a lover - constantly. I've read/heard somewhere that the best way to find a solution is to not work directly on a task but doing something else instead. Problem will most likely solve itself in our heads, then we get to execute the idea.
And I really do recommend to carry a notebook literally everywhere cause we don't know when the fun idea or a solution to the problem will appear!
