Honey, it's kind of like going to a therapist. She can't help you unless you bare your soul to her. Same here.

Don't be ashamed. I've walked several miles in your shoes too. As a matter of fact, worn out a couple of pair of boots with all the walking! LOL.
And you've taken a first step toward credit recovery by coming here and asking questions.
RE: the med collections: It may be charged off and assigned to a collection agency, but that doesn't necessarily mean that the hospital still does not actually own the account.
I had 2 med collections from a hospital dating back 3 years....into collections. I did all my negotiating with the hospital by offering to pay in full with cashier's check if they'd remove the baddies from my cr. They agreed and they did remove them.
If the CA does in fact own them, then you have to negotiate with the CA. Offer to PFD, but DO NOT commit to anything just yet, unless of course they accept. They are very intimidating. It might help to give dates, amounts, and name the CA when talking about it here.
Cap1 might prove to be more of a challenge. Never dealt with them in such matters. Other here might have and will contribute their experiences.
