Insecure 😕 updated

Does anyone else feel like having kids made you really insecure and jealous over everything with your SO? i'm almost to the point of wishing i never had kids cause i just feel so awful about myself, like i lash out, say crazy things, do crazy things. i'm just not myself anymore. after my daughter i was like this & now just after baby #2 it's even worse (5 weeks pp now). i haven't been diagnosed with pp depression. will this feeling ever go away on its own?
