The PMP Eligibility criteria are clear:
- You need 4,500 of diversified project management experience (but you don't need to be a project manager)
- You need to a have a university degree (or else you will need to accrue 7,500 hours of PM experience)
- You need 35 contact hours
There is no way you could have accrued 35 PDUs (I guess you mean contact hours), you can only accrue PDUs after you become a PMP, and not before.
It seems to me that you are eligible for the PMP, you don't have to have current work experience to apply, and your past experience in PM will be counted towards your eligibility, provided you have worked on real projects.
