How Can I Be a Better Parent When I Feel So Broken?

Long Post. So Ive been on this app for years & almost never post Anything. I have a 5yo daughter that i love to death & she means the World to me…. But im just soo miserable. Im always sad, depressed & just not happy with life, i have a therapist & psychiatrist & have been prescribed a multitude of medications but i still feel soo broken … literally too broken to be fixed. My daughter is Such a ppl person & im not . I have really bad ptsd & trust issues & just completely isolated myself. & I’ve practically just no interestin doing anything. But my daughter wantts to constantly be around people & do stuff, which im not upset because she deserves all of that . But i just feel like im not mentally in a position to give her that. Lately I’ve been Leaning heavily towards just giving up …. I mean i almost kinda have my mind made up . I feel like a terrible parent for being miserable & not able to enjoy life but i feel even worse for not wanting to be here anymore. It’s to the point it feels like my baby doesn’t even want to be around me . Idk what to do . Im desperate & literally at my wits end 😓 im not eating, not sleeping just can’t focus. I almost feel like im not even myself.
