Idk what to do

I’m 3 months pp. My postpartum depression started a month ago. It got so bad I had no choice but to ask for help. I’m on meds now and I’m not crying all day and I’m less overwhelmed but I feel like there’s this huge volcano of emotions stuck under a medication cap. Like if literally feels like the depression is masked..Idk if that makes sense. It’s almost worse in a way because I have no idea when it’ll erupt or how bad it’ll be when it does..my depression feels there but my bodily reactions are different. I don’t know what to do. I just want to feel better so I can be a good mommy to my three children.
