feeling guilt for getting pregnant

I have a two year old son who is very active. And I'm feeling very emotional right now because due to my symptoms all I wanna do is lay in bed and sleep I have no energy at all. I feel so guilty and I been balling my eyes out because I feel like I'm neglecting my baby😞 he is my life! I'm having intrusive thoughts about my pregnancy like wanting to misscarry or terminate which is something I would never actually do but these emotions are real. I don't know who to talk to about this. I feel like I let my son down by getting pregnant😞 I'm currently 8 weeks. I had zero symptoms with my son so this morning sickness all day sickness is getting to me😞 I was on antidepressants but stopped as soon as I found out I was pregnant and I don't get to see my ob until monday😔 I just want these 4 days to fly
