Anxiety, in my experience, does not usually cause visual disturbances, at least, not to the extent you're describing. I would suggest a check up with your OB/GYN, your PCP and possibly an EENT. How much alcohol are you consuming and are you on any medications? Are you getting adequate rest? How is your diet?
If all of this only began after the birth of your daughter, it could possibly be some hormonal imbalance, but only your doctors will be able to test for that.
Maybe someone here can relate, but your symptoms need to be addressed by a doctor sooner than later.
