When I'm down or stuck in a rut, I've a tendency to stay away from people, moreso than I already do, until I've pulled myself out. Being around people, even my best friends, is just additionally draining when I'm in that state.
When I'm under direct emotional stress, I don't get a sense of emotional release from breaking down in front of people I'm close to. I rarely seek comfort from others. This also carries over to when I'm generally feeling exanimate or listless. I can't be motivated through interaction with others when I'm in that funk. I need to be by myself in order to process everything, and recover my internal drive.
Typically I seek inspiration. Hang out in my cave and try to remind myself why I wake up in the morning. Usually read [some kind of scifi/fantasy or philosphy/articles on psych] to clear my head, write, and listen to music. Sing along. Watch a musical. Theatre is a huge passion of mine, as is psychology and, well, just learning in general. Frequently that's the ticket for me, and I'm able to get around or "snap out of" whatever in the present is bothering me. Focus on the future and whatnot. It's very much like a light switch.
Once I'm feeling better, I gravitate toward people I can leak out my inspirations to, and exchange ideas [about literally anything and everything and nothing], and talk about their dreams with as well.. mainly with INF/TPs. And my INTJ friend is great... we discuss our "master plans," & debate everything from science & philosophy to the purely inane, hypothetical situations [like if and why an iconic hat would truly be necessary for the future ruler of Mars]... and he makes me laugh... at myself. Occasionally my ESFP friend will bring the unadulterated ridiculousness out of me. I like to make her laugh... and pull her into what she likes to call "heavy and deep bestfriend talks." She brings the ADHD-i-wanna-scale-buildings, sugar-crazed kid out of me, and I bring the dormant, deep-thinking philosopher out of her. Interesting give-and-take right there.
Eh, for me, when it comes down to it, it's all about the rekindling of passion, zest for life, in some form or another. Corny as that may sound.
Oh. And my cat. Of course.
