Of ex house "guests", cast iron skillets, and thinking I'm losing it....

Finally, FINALLY, the wife and I "lost" our house "guests". Just shy of 7 months, and we now have the place to ourselves. It was getting stupid. Both parents aren't able to work, one has heart troubles and the other back. The 14 yo daughter was becoming a bit too much of an adult and overstepping her bounds and being mouthy. And all of them seemed to lose track of who's house it was and their role in it. Food is a good example. I like certain things, and when I purchase them, I expect them to be MINE. They didn't respect that. So much in fact, that when they left (and no one was watching them...) they actually took a whole package of something I had just bought to get me through a week's worth of breakfasts. And the hassle of just having them here....One night I went to get my dinner (one of the few times they cooked it) and he was in the kitchen. Well, I grab a plate, and start towards the stove top, when he steps in front of me to grab something I was tired and not in the mood, so I simply put down the plate and left the kitchen. He asks "what's the matter?" I told him nothing and that I would wait for him to finish up. A couple minutes later, he tells me that he's done, so I go back in, only to have him cut me off at the refrigerator. I nearly lost it at this point, but I backed up, let the plate down hard enough to serve as a warning, and walked out again. He's like "OK, OK, I'm done." I told him until he was sitting on the sofa where I USED TO SIT BEFORE THEY MOVED IN, (he had taken the spot over) that he wasn't "done". I waited another 5 minutes for him to finally sit down. I had to heat up my food in the microwave. After that, if I was in the kitchen, I made it perfectly clear that NO ONE else was to come in until I was done.
Safe to say, these people, despite being family, were getting on our last raw nerve. Thank God they're gone. I really do hope that we don't have to visit with them socially for at least a few months, I don't think I could be civil in light of everything. It's amazing how much these people took (conceptually) from my wife and I.

Good thing....I think I have my new cast iron skillet seasoned enough. Been using it as much as possible for the past couple days, and only washing in hot water, and then Crisco and a hot oven for half an hour. Did my first skillet 'cakes for breakfast this morning, and OMFG was it wonderful! First time the eggs didn't stick either. I will not regret that purchase, in fact thinking about getting a couple other sizes. Already thinking about skillet cornbread.

And a not so good thing....I really do wonder if I'm losing it. I don't "feel" stable anymore. I used to be full of confidence and pride, and now on not so good days, I just feel depressed and low. I mean, I still feel OK, but I second guess myself, and just feel like I'm not as good as I need to be (vs not as good as I could be, which alarms me a touch.) I kinda obsess over what others may be thinking about me, but not what I feel is harmful, but I didn't do it in the same way I do now. I feel it's hurting me in that I'm wasting time worrying instead of dealing and improving. It's a million little things all mixed in with a couple big ones, and I'm not sure of the order and direction necessary to put it into perspective. It's like I've got a gear with a missing tooth, and on occasion it skips and puts me off for a couple revolutions. I do have my good days where I can tell myself that "Hey, that went really well, I'm not doing so bad." And that really boosts me, keeps me up. But when something doesn't go quite right, it can really put me in a funk. I'm not forgoing my interests or hobbies, except that the midnight shift keeps me from them, so I know that I may not be too bad off, but I still wonder just how messed up I am. So yeah, I'm probably going to look into a counselor and see about getting that broken tooth gear fixed. I hope I can get this straight, 'cuz I really do miss feeling "normal".
