Possible VSD on 20 Week Ultrasound

Anyone gone through this? My doctor said not to be worried but I’ve done my own research and it said this could be linked to a chromosome issue. I asked my doctor about this and she set us up with a genetic counseling appointment for our own peace of mind. I’m trying to keep a level head but I’m absolutely beside myself - I have had debilitating anxiety and depression this entire pregnancy where it feels like I’m constantly waiting for the other shoe to drop and this feels like it could be it. Has anyone else had their baby diagnosed with a VSD and it not been linked with a larger health issue?
