Hello friend. I think that I've been there as well. I worked in a dead retail job for quite some time until recently when I decided to go back to school online. At the same time I became engaged, traveled abroad for the first time in 2020 in late February and almost got stuck in lockdown, worked overtime prior to and following coming back to the states, and started my first internship. About the same time, I started to sleepwalk, to develop an eye twitch, and to develop lockjaw.
I had to consciously relax my jaw and eye while at work or when thinking about work.
I'm going to say something cliche: have you tried therapy? I know quite a few people recommend it online, but finding a good therapist can be hit or miss. It may not be covered under health insurance or might be stigmatized. However, I'm not trying to dissuade you from therapy.<p>I cut back on my hours at my retail job, stopped picking up extra hours for money, saved up, finished my internship, put in my notice, got married, and took an unemployment sabbatical I guess you could say. I found a new job and completed my degree with a less stressful work environment, and I am much happier. When times got really tough I had my wife and best friend to talk to. My friend, when he was struggling in life, took up weight lifting, and he seems in a much better place now, mentally speaking. I might suggest based on this anecdote taking up some form exercise if you don't already.<p>If I were you I would try to identify the source of stress in my life and reduce exposure to that thing or find someone who'll just listen while you complain for a bit. After getting off work it helped me to have a ritual of some kind to change headspaces or to engage codeswitching. As it's been explained to me, symptoms such as lockjaw or CSCR manifest as your body's way of telling you that should current conditions continue your body will receive more trouble, especially as we age. Maybe all you need is a break?<p>As to the right amount of stress or finding a balance, I haven't figured that out yet. Best of luck, and I wish you well.
