I suck at praying

I honestly sometimes feel like such a “fake Jew” sometimes because I’m just not good at praying. I’m not sure if how I personally pray makes me invalid as a Jew, I guess I’ve just never been one to like to speak to Gd out loud or at least above a whisper. Maybe it’s my way of keeping it between us, like if it’s a specific prayer about something I’m going through, I’m not sure. But I just suck at traditional Jewish praying and it makes me feel so invalid. Does anyone else experience something like this or is it just me??
