Feeling alone

I have a huge support system yet I still feel so alone?? I’m 6 weeks pregnant, I feel sick everyday, can’t stop crying and just feeling very miserable. I’ve never been pregnant before so this is all so new to me and it’s just a lot right now. I’m starting to have 2nd thoughts and I feel so guilty about it. I really don’t know how I’m going to do this for 9 months.
