Like @Paulette , I am also extending a warm welcome to you @Dawnann25 ,
Welcome to the forums and making your first post!
It takes a lot of courage to reach out and share your experiences to an unknown community.
I'm sorry you are finding this so tough at the moment. I'd encourage you to monitor how you are feeling, seeing as you are 21 weeks pregnant. Your hormones may be going haywire which may contribute to how you are currently feeling. If you feel unsure, please reach out to your GP.
In the meantime, as @Paulette has mentioned, do you have other supports in place whom you can confide in?
If, at anytime you feel you need a chat, you are welcome to contact our Drop-In service to speak to a counsellor on 1800 187 263 (M-F 10am-10pm). Webchat is also available https://www.sane.org/get-support/drop-in-service
Looking forward to hearing from you.
