I lost nearly three liters of blood due to my placenta breaking I feel I’m going to pass out

I’m 23 and female. I had a baby 7 months ago I lost nearly three litres of blood due to my placenta breaking, o had one blood transfusion, since then I’ve been constantly dizzy, I had iron pills they says that’s fine now had low blood pressure that’s okay too apparently, I have anxiety they usually put it down to that or me being exhausted as I have two children by myself but I know it’s got to be more as I’m dizzy all the time it never goes away, to the point I feel I’m going to pass out it’s scary especially when I’m alone with my children I really need something to help with my constant dizzyness
