Breastfeeding advice?!

I had my sweet little boy on 19th May and chose the epidural as my pain relief through labour, however I then suffered with post dural puncture headaches and had to be readmitted to get the blood patch done! I had to stop breastfeeding and start substituting with bottled formula however I still want to breastfeed once I’ve been discharged from hospital in the morning, is this going to be possible or are all chances of that been ruined? I’ve not been able to pump so has my supply been ruined too?

Thanks.
