Parenting is undoubtedly very stressful, so try to take a few slow deep breaths. Your description does not sound very unusual to me.
You may want to check out this link to a Dr. Sears site, it talks about fussy babies. {My first daughter was fussy & I bought the book.} Hopefully, there is some helpful information for you on the site.

Very best wishes to you and your son ~ take care!
