I have suspected that DS (who will turn 8 in a few weeks) has some anxiety for awhile. He is very sensitive and we don't watch the news or the weather channel because he can fixate on something and starts to worry/repeatedly ask questions/etc.

Over the past month or so, he has gotten frequent stomache aches--usually at bedtime, first thing in the morning and sometimes in the car. He's had lots of issues over the past few months--horrible stomache virus in November and an appendectomy in early December. He has checked out fine physically. Yesterday, his teacher called and said that he was clearly in pain. I picked him up and took him to his doctor who says she suspects anxiety. Last night, he told me he got sick in class because his classmate explained "Five Night's at Freddy's" to him. (I had to google this). He had trouble sleeping last night and looked exhausted this morning.

Any advice? Book or article recommendations? Thank you.
