Thanks for your query. The symptoms you report of anxiety
, bodily symptoms lack of energy and fatigue
in the aftermath of a stressful life event point towards an underlying chronic depressive disorder or somatoform disorder
with an overlay of depression. I would suggest you undergo a thorough psychiatric evaluation for the above disorders. Lexapro is escitalopram, an effective anti-depressant that should work in any of the above disorders. There is always scope for increasing the dosage substitution with other anti-depressants as well as psychotherapy
(eg cognitive behavioural therapy). Hence there is no reason to lose hope. Wish you early recovery.
