It does take some time for the body to get back to normal after the depression lifts....3 weeks is really not a lot of time......but it's also good to have a baseline knowledge of what's going on with your body such as blood tests & everything else they can do.

I went through a trauma with the home care person when my mother was dying of cancer....ended up causing my weight to drop so low it was considered anorexia.....my gp stuck me in the hospital.....in & out for almost 2 months because I was so sick from the stress that I couldn't eat. He did every test possible in the hospital to prove that it wasn't something physical......even though I told him what was going on in my life. Nothing showed up to be physically wrong.....but it was good to have the tests to prove that also.

Blood tests can show up a lot of things that can cause problems.

If you are on meds, some of what you describe I have found to be side effects of meds.

One never knows until we sort through the facts about our bodies & blood tests are a good place to start....then go from there.
