am I having anxiety or just being ungrateful 😥

So I have a 7 month old and last month we decided we wanted another little one I am now 6 weeks and 4 days pregnant but I also have HG meaning my nausea is 10× worse than a regular pregnant person...i am now over thinking asking myself how am I gonna get thru this bc with my last pregnancy I definitely went thru hell and back and now I just keep thinking I didn't thought about anything else EXCEPT wanting another baby now I'm sitting here next to the toilet puking my lungs out 🤢😷 asking myself did I do the right thing but now is too late to turn back im pregnant there's no turning back but to deal with it!!!
