Postnatal anxiety?

I'm 10months postnatal now and have been treated for anxiety, depression and PTSD in the past. Haven't been medicated in 4years and finished treatment about 2years ago.

Since the baby's been born but more recently since he's more active and moving around, getting bumps and bruises as he learns to stand and walk, i'm just terrified that social services are going to come take him away from me.

I have no reason to think social services would get involved, no history with them myself or partner or even family.

Just everytime he has a bruise I panic they'll take him. If he needs to see a Dr I panic if he has a bruise incase they refer him and think I'm doing a bad job.

I hated taking the medication in the past it didn't really help all that much, I'm also still breastfeeding but I don't know when to say this is a problem now.
