To the OP.....
It seriously sounds like you're suffering from burn out. I hope you get time off soon so you can take care of yourself as well. If we don't take care of ourselves, we can't take care of others. Our pt/residents DO sense the stress and frustrations that we all have when we get burnt out (and we've ALL been there at one time or another no matter what setting we work in) whether we feel we are hiding it well or not. Dementia pts pick up on this VERY well and they will act out because of it!
I love working LTC and wouldn't change my setting! However, I understand you're frustrations all too well!!! Unfortunately with the economy all healthcare facilities, including both LTC and hospitals, are cutting back on staff. I left my last job because they not only were cutting back on staff, but were admitting the most acute pts and expecting us to do medicare assessments, change of condition assessments (there were many days that I had literally 15 full assessments), 2 admissions, a discharge or two, 6 different IVs, a tube feeding or two, 15 treatments/dressing changes, 2 med passes, new MD orders and taking care of the crashing resident, the fall, the low BGT, the new skin tear, etc all in 8hrs. I think you get my point. Its places like these that you need to do your best while your there and look for something new.
One thing I encourage you to do is really concentrate on your assessments. You actually can gather a lot of info in a short amount of time. It is in LTC that you will really learn to hone into those assessment skills as you are literally the eyes and ears for the MD. It is YOUR assessment that gets the residents the care they need. There is no MD in house to come check out a resident when things start going wrong. I also find that in LTC you do learn a lot about many different disorders/illness. And you get to see the disease in progress. many times start to finish - You can learn A LOT from this.
I wish the best of luck to you! I hope you find your niche. Don't count LTC completely out - there are good facilities out there!
