Thanks for the reply.
Well, from what you have mentioned , i believe you are suffering from What is called as Atypical Depression, as the symptoms you had mentioned fit the diagnosis quite well, and that is why i asked you few questions to confirm it.
However , there is nothing to worry, it is just that you need to consult your doctor /GP and you shall discuss with him the diagnosis i had proposed , as well as the treatment regime that i am mentioning below.
1) 1 Anti depressant needs to be started , keeping in mind , that your hands are full , taking care of your two small kids and outside & household activities, so i would suggest you go for either Venlafaxine ( Effexor XR) , OR , Paroxatine (paxil). Both these are quite safe drugs , and will not cause you any sort of sluggishness or sloppiness, in fact, once you have been sustained on them , your lethargy , lack of energy and other related symptoms will also go away. You need to take any one of the two mentioned drugs, let your GP decide on the dosage and the time of intake.
2) 1 Anti anxiety drug such as a clonazepam (klonopin) or buspirone (buspar) or lorazepam , any one of the three mentioned, needs to be added to the 1 anti depressant. Again the dosage and the time of intake needs to be decided by your GP.
A word of caution , these psychiatry drugs are not to be taken during pregnancy , since you are in a child bearing age group, and if you are thinking of pregnancy then you need to discuss about the use of these drugs to the gynaecologist .
So, i suggest you discuss the probable diagnosis and the treatment regime with your doctor and get started on the treatment as soon as possible and i believe you would find a positive change in your health after a while.
Wish you all the best.
I hope my answer serves your query according to your satisfaction.
