Whoa. Anakin leaving his mother doesn't spark constant fears. He's sad that she's not with him, but not fearful. The fear creeps in when we get to Episode II and the dreams he has....
Second, Anakin does ask the Jedi, in a round about way. He can't reveal specifically the attachment he's having dreams about but he does reveal it to Yoda, before Palpatine tells his "Sith" tale. Plus, remember the funeral of Shmi in Episode II. He specifically states that "he wasn't strong enough to save her and that he won't fail again." Why does he have such thoughts in this way? Because, he believes he's the Chosen One and that he can and should be able to do anything....hence the resentment he has toward Obi-Wan and the Jedi for "holding him back."
