how to deal with stress?

I am so irritable lately. In a bad dip of depression and anxiety then hit with a financial crisis that left me so stressed I can’t think. The DDs came on so strong and I was so weak from all the stress that it has tormented me ruthlessly. I am at a loss of how to regain my sanity. I tried walking but it just increased the anxiety, I can’t be still enough to meditate. I just want to scream. I may have to give in and take a nerve pill. I wish I could do something.
