Is the sentence correct-shopping is a great medicine for frustration sadness loneliness?

I realize that the 'question box' does not allow using correct punctuation, however, it does allow you to use capitals when needed. Now, the main problem is the punctuation; corrections in bold:

'Shopping is a great medicine for frustration,sadness, or loneliness.'

'Shopping is a great medicine for frustration,sadness, and loneliness.'

Note: Although I've corrected the sentence, the statement made by the sentence is not correct. Shopping under those circumstances will lead a person into trouble, both financial and emotional. Spending money to feel better is bad medicine.
