sorry about your wife.
the answer is yes, it can be beaten. but it should not be taken lightly. no drugs or alcohol, not saying you drink or take drugs but it enhances the symptoms. try to be around those who care for you, friends/family. most importantly would be some counseling, it helps. lastly, time. it takes time and you have to do everything in your power to keep your chin up and remain as positive as you can.
good luck to you. reaching out is the first step.
doing good for others is always a good thing. reminded me of a video I had seen not too long ago. pretty cool
