Persistent Depressive Disorder

Is there any hope to cure PDD?

I’ve tried over 10 years of therapy. I’ve been on medication for 1 year. Currently at max dosage of Zoloft. I’m doing EMDR treatments.

The strength of the depression comes in waves. Currently I don’t feel like there is anything to look forward to. I don’t have an appetite and no drive to eat. I just want to sleep all day. I can barely function or complete tasks at work.

I’m worried I will lose my job. But I have to provide for my child. 34F.
