Hi there, thanks for asking. Depression is a situation that is related to social factors, biological factors and psychological factors. If you have problem with work or family, the medication will not work as well as the normal situation. The symptoms you mentioned are a combination of anxiety and depression disorders. You can practice Yoga or medication and other methods to decrease your anxiety level. Your function will improve just in few weeks. You can consult your doctor to see if he can increase the dose of your medication a little. I wish you the best.

hello

welcome to health care magic

You probably have "major depressive disorder". All the symptoms mentioned by you like feeling depressed, feeling rotten stomach, disturbed sleep, suicidal thoughts etc are indicative of depressive episode. Sweating when feeling cold could be due to associated anxiety.
Lexapro contains escitalopram which is an SSRI which is quite effective as antidepressant. But for its full efficacy, you have to take it regularly (no gaps) and that too for adequate duration (6-9 months at least). However, discuss all the stuff with your treating psychiatrist and have full faith in him.
You may also require psychotherapy sessions and relaxation exercises.

Wish you good health
