Why do I feel like this

Now that I’ve started looking for god more i feel like no matter what I do I still feel bad like what ever I do is not enough like praying and reading the Bible sometimes I just feel desperate because I don’t understand a lot of things 😢 I feel alone a lot of those times ...even when I do get down on my knees to pray I have so many thoughts running through my head I can’t even concentrate ughh I’m sorry I just want to know if anyone has went through this
