Well, so, long story short, this time I didn't drop the tech class, I withdrew. I'm working on getting a medical withdrawal, per the advice of my advisor. I'm not feeling particularly good about it, but there has just been an unusual confluence of events over the past year and I think my body, mind, and spirit just need recharging (and perhaps a bit of medicating). I always wondered about people who would do this kind of thing when they were ONE CLASS away from graduating, but now I guess I kind of get it.
The good thing is I'm feeling more enthusiastic about my job. I think one of the hard things was going back in January for the first time since last September. While I had the practicum in the late fall, there was lots of flexibility there. Resuming work again at the same time this class began and then having two family health crises in January was a bit much...and as these things go, they didn't play out the way I thought they would. The one I thought was the most immediately serious seems relatively resolved, and the one I thought there was time on before it created problems started being difficult right away.
I think there was also the matter of the changes at work. While those started in the summer and became more pronounced in the fall, I really didn't have time to acclimate to a lot of things before I was out for a few months. Now that I can concentrate on just my job, I'm starting to feel more comfortable in my surroundings.
I will finish this, though, because I really want it. I will use this time to develop and work a strategy for getting this done. I also need to think about strategies for handling challenges that seem to come suddenly from several different aspects of life. I also need to maintain my optimism in what seem like not very good times. Luckily, my husband is pretty good at offering perspective. It's nice to have someone who has been through a few existential crises of his own to see me through mine.
