Welcome.....as the others have replied,sorry about your wife.
Seems to me youve been through alot ,big things like loss can really throw anyone into an emotional mess.
Although you are having difficulties, I admire that youve been able to hold it together....esp with kids,thats gotta be tough.
Is it possible that your meds could be tweeked a little?
Have you talked to your pdoc about an adjustment?
Its always good if you can at least talk to him/her about options.
Hope you find pc a place of comfort and support.
