What is the most effective yet least dangerous drug for anxiety?

[Person]

Anxiety has seriously been affecting my life, but as much as I want to help ease it, I also don't want to have any side effects. I tried the herbal antidepressant called Panicil, but that didn't really work. I went to a psychiatrist and he recommended Celexa, but the sexual side effects bother me. I heard that it is effective, but even so, it's not worth it. Part of my anxiety is because of sexual issues, so this would make it much worse. I definitely want an anxiety medication without any sexual side effects. I also would like a medication without weight loss/gain. Please correct me if I'm wrong, but I heard that headaches, blurred vision, constipation, and other mild side effects are temporary and only occur in the first couple weeks, but if not, I wouldn't want that. I also would like it to be okay to take during pregnancy/breastfeeding. Please help me, and thank you!..
