11 weeks pp.

And my anxiety level is high, I started 5 days pp. It has got worse over time to now I don't want to drive bc I'm afraid I will have one while driving. And when I think about panic Attacka, I have one. I feel tight in chest light headed tingling all over like I'm gonna pass out and hyperventilate. I have been on prozac 20 mg for 2 weeks now I tried to drive today but I felt like passing out again. I'm fine till I drive. Ugh I just want my life back. :(

When should prozac help
