Anyone dealing with postpartum anxiety

I feel like such a failure... I just had my 3rd baby 9 days ago . And I have let anxiety take me over . I have a pre-existing anxiety disorder . And it was really controlled with meds while I was b pregnant. Well I wanted my self off with my doctor's okay and was doing well. Every s since I had her I have been crippled in fear I was at Wegmans today and took my blood pressure and it was 160/96 I called my OB they had my come in right away. It still was high in office but urine was clear and after sitting it went down to 135/76 . They sent me for blood and want me to come back tomorrow for a recheck. But the nurse said it was a great sign it came down and it was probably anxiety induced. I did restart the Lexapro about a week ago . Tell me I'm not alone
