Thank you so much for the offer. Not sure what PM is? Private messaging?

My biggest question is whether I should put a reason for leaving this last job.

The sad thing is that I've worked in management and even had Human Resource experience before, but I'm so down on myself right now that I don't even trust my own opinion.

I tailor the resume (pointing out accomplishments, etc.) to each job I am sending to. Also send a cover letter that points out the areas of skill and experience that most apply to the job I am applying for.

I'm going to give myself until June 15th (get medication regulated, etc.), then I will either start temping or find a job in retail or something. Was working part-time until recently for the friend mentioned in #4 of my post. I think that was the final straw - big mistake (working with/for a friend).
