Yeah, Psalms is a good daily thing you can do when you don't feel like doing much else.
My mother told me to read a psalm and proverb a day...I did. They are deeply sown into my mind...to the point where when I pray some heavier things I know he's heard the depths before and I'm not uncomfortable about it.
Psalms are great for seeing the depths of the human experience...the spectrum if you will.
If it gets too heavy or seems too "remote" for where you are, that's when I used to jump to the gospels.
I also agree with what others have posted as a good starting place. I'm not sure where I started but I also grew up in church...I do distinctly recall a time when I was 14 making it through each of the four gospels...it opened up a lot and was an excellent refresher.
I've read different books in different seasons...so I can't tell you what specifically to read, other than the New Testament is a bit more plain on certain things. In some sections of the Old Testament, it is almost as if you are expected to understand.
What's cool is that more than a few portions of the New Testament repeat the Old testament (like an overview) for context.
Everyone is different though. Lots of people on this forum are open to helping if you get stuck
