Terrified all the time

I am constantly scared something is going to happen to my lo. At first I thought she would just stop breathing. Now after going to the docotor I still think that she's having seizures. I know the twitching is normal I just google/read way too much. I hate feeling this way but I can't help it. I've talked to my doctor and started medicine but I feel like all its done is Stopped the crying and huge huge panic. I want to enjoy this time not second guess every little thing she does
