Bless your heart -- I am so sorry for the loss of your dear wife. My heart goes out to you. But PLEASE know that drinking will only make it worse as alcohol is a depressant. I hope to God you are not still drinking. If you are, please try AA as they will help you to get sober and stay that way!
And I'm certainly glad you're seeing a psychologist too! He/she will definitely help you thru this trying time. Be open and honest about everything, and you'll definitely begin to heal.
Again, my thoughts and prayers are with you. Please keep us posted on your progress, will you? God bless. Hugs, Lee
