This a good time maybe to write a list all of the good and wonderful things she does. Of things that you appreciate about her. Give her this list and try to talk to her. Offer her since apologies.
Explain to her your shortcoming and the plan of action you have for getting help and changing.
Tomorrow frequently thank her for small takes and do things like let her know that you enjoyed her meal. The shirt is a nice color for her face. That she did a good job as a mother today. etc

She is hurting and actually she needs you to be there for her. The worst thing you can do is retreat from her. Unless she requests her space. I think it would be best to try and engage her, IMO.

She knows about the clinic?
