Scared of being a bad mom...

Before you had kids did you ever fear like you were going to be a bad parent? I want kids deep down but I’m terrified I’m going to raise them badly. I have a bad relationship with my mom and never really felt loved by her, she’s always angry and in a bad mood and I feel like I might treat my child the same way because im starting to act like her in terms of anger. I don’t want my kids to be afraid of me or not like me. I dont want them to be suicidal or depressed like I was. It’s so scary !!
