TTC has made me someone I don't recognize

Hi there, my partner (32m) and I (31f) have been trying to conceive for a year. I have since been diagnosed with very very mild PCOS mostly by my irregular periods and that I have a few anovulatory cycles a year and late ovulation. Back in October, both of my best friends got pregnant it was hard to support them while also being so envious of their situation, they both got pregnant the first month they tried and are both due within a week of each other. In December, I found out I was pregnant and I was over the moon, then I had a miscarriage at 7 weeks and it totally broke me. After consulting with a fertility doctor, he decided to put me on medicated cycles (2.5mg Letrozole) in order to help regulate my ovulation and give me a better chance to conceive. In addition to fertility support, I have a therapist and a psychiatrist who has put me on SSRI's to help cope with everything and I have a really good support system in my husband and family. My husband and I are even in therapy to help us manage this situation. Everyone around me is telling me I am coping well and making really good progress. But I cry every single day and the miscarriage and my TTC journey haunts me. I don't even recognize myself, I was this very outgoing, bubbly, successful person and now I can barely leave the house without severe anxiety. I have a hard time talking to anyone because all my brain can think about is TTC and the miscarriage and I know people are tired of hearing me talk about it. I was just so ready to be a mom and now I feel like I am in this place where I will be a bad mom because of how emotional this has made me. Not sure what I was looking for by posting this, just having a bad day. ty <3
