Is pregnancy harder in your 40’s?

Hey mamas, looking for input. I’m 41 just entered my 2nd trimester. My first pregnancy to make it this far. Since 7 weeks I’ve been so sick, experienced all day morning sickness etc. Now I’ve been experiencing extreme anxiety. I’m not sure if the anxiety is due to feeling sick, or if it’s anxiety due to fear. My girlfriends who are pregnant are enjoying life and dont seem to have any of these issues - they’re also in their early 30’s.. Are any of you AMA mama’s experiencing same or have experienced same? I’m at a loss. 😢😌
