Am I complaining too much to Allah? How can I stop this?

For any bad or mishap I complain to Allah a lot. It feels like I am pissed and just blaming him for everything. But just after that I feel bad and start doing Istigfar. I wanted his help, though I always need his help but that day I felt very bad due to some bad events. And I started to feel like my Allah is leaving me alone. I felt scared. I started to complain even more. I just wanted to know if at some point most of us complain to Allah. Am I gonna get mercy from him for my nonsense complains? Thank you.
