I need a pep talk or a reality check, idk which.

We have been TTC for a little over a year now. I know in the scheme of things it's not long but I've been wanting to start a family for years now. I get a tinge of jealousy when I see pregnancy announcements then move on with my life. My friend just had her baby and I am so happy for her but also heart broken. I want a family and I feel defeated. My husband says I need to live in the moment and not worry so much about what's next. My friend says I need to stop idealizing and letting trying to get pregnant consume me (she does not want kids). Other friends who have taken years to concieve tell me it will happen. I'm tired of people telling me to 'chill out' basically. I just feel like it's not ok for me to have emotions and I have to pretend I'm not going though an internal struggle. I dont know how to handle these feelings because I cant rationalize them. Any advice would help.
