Hi Sandy65

I have no experience of OCD or GAD but I do live with MDD.

As well as medication, I have found that using Cognitive Behavioural Therapy and mindfulness/meditation methods, which my clinical psychologist taught me, helpful.

I used to go to a therapy group for people with mood disorders. Other group members, with OCD and/or GAD, reported that these methods were beneficial for them.

Perhaps they are options which you could consider?
