Your emotions will fluctuate for a while as you and S11 adjust to a new way of living apart from W at the condo. Those feelings are normal as you and S11 forge a new life together.
From where I am sitting, W is being reactive to not having you and S11 around so she's reaching out a bit frantically. Nothing wrong with that as she's probably emotional about this as well.
There will be opportunities down the road for you to connect with W. Now is not the right time as you need this break for your own mental well being.
A word to the wise about hiring a credit repair company. Be really careful as some are scam companies. I personally feel that most people can do it without hiring a credit repair company. Just need to order a free credit report from all three reporting agencies and take a look at it for any errors. If there are any errors, then write to the company disputing them. Also suggest that you check out the Consumer Financial Protection Bureau's website as they have great information and resources for you.
