Hello, I'm sorry that you're having a hard time. I know what you mean about the situational depression. I've had some pain most of my life, since I was apparently born with TMJD, but they didn't catch it until June 2010, when I was 39! The pain used to be intermittent, but has been constant since early 2010 - the CFS and FMS and my other seven dx's all make life hard, and while I'm not dx'd with depression, I do go through bouts of it when everything catches up with me sometimes.
I say, keep asking for/saying the same things over and over again until the doctors do something else to try to help you. My pain management doctor believes less is more - she actually doesn't even tell me when she dx's something new, and when I ask for things like injections or B12 shots or anything else she will usually say no for a year or more before she finally does it. We definitely have to be our own advocates.
One thing I am grateful for is that my kids were both young adults by the time things finally took me all the way down, so they remember the go getter that I always was before. However, our son (21) moved back home last January, and I was pretty stressed about it at the time because even though he knew I had pain, I didn't want him to see what my life looks life day to day.
Easier said than done, but just love your kids every day and spend times doing things with them that don't take up much energy. Time reading, singing, playing cards or just talking have a huge impact, and are something that often times healthy parents don't slow down enough to do.
I hope you have better days coming and that the doctors will finally listen to you and be more proactive.
