I just need to vent

I’m in absolute amazement of the way I was mistreated in a sperm donor group. I am single so decided to go this route. I posted my age (18) and people started bashing me that because I was not at drinking or smoking age I shouldn’t be having a baby and that because I was going to school I also shouldn’t have a baby. I am in complete shock and anger. One guy even had the audacity to say that I should find a donor with a lot of money because it seems outrageous that I wouldn’t have enough money to support my baby. Has anyone gone thru this!
