Welcome to the site.
I am Dr. Kaushik and I believe I can help you with your problem.
Well it seems after reading your symptoms that you are suffering from depression which can be managed by use of herbal remedy like St. John's wort at dose of 300 mg of 0.3 % hypericin extract to be taken three times a day. You shall give this remedy around 1-2 weeks to show it's effect on your depressive mood as this much time it will take to settle in your system.
After 1 month on this remedy if you have not improved at least 25 % overall in your symptoms then you shall come off it and try out the conventional anti depressant drug like Lexapro ( escitalopram) at dose of 10-20 mg / day to be taken in the morning or wellbutrin xl ( bupropion) at dose of 150-300 mg / day to be taken in the morning. This shall surely take care of your condition, so this can be used as a back up option but first you may give st. john's wort a genuine try and remember that you should not miss a dose after you have started on it since it may lead to precipitation of withdrawal side effects which although temporary but are distressing enough to make the condition worse.
I hope this helps.
Wish you all the best.
