Hi David, I Have Recently Been Plagued With Uncomfortable Anxiety

Hi David,
I have recently been plagued with uncomfortable anxiety and feelings that are relatively new to me. They have existed in the past in a much lesser form, but have transformed into something that affects my daily doings. By self diagnosis I have chalked it out to be a mild form of PPD. I don't believe it to be a disorder at this point as I feel I still hold control over some of it. But, I am wondering how I can lessen and soothe the paranoid thoughts about things that I so often have.
