I’m scared to be happy

So I’m almost 6 weeks guys after ttc for 10 years. I’m kind of in a weird place... I’m happy n soooo excited yet I’m terrified. I want this baby soooo bad . I believe god wants this for me but I’m afraid to b over the moon happy because of the unknown ... once I make it past 13 weeks I know that I can than b soooooooooo excited ! Like pee on myself excited 😂🤣 but for now I’m trying to stay calm n be ready for whatever is to come. What r some tips to ease my mind
