I can sympathize with your situation, and may God bless you in the journey.
I too was raised to take the first 11 chapters of Genesis as literal history, but I came to realize that viewing it literally is not consistent with the evidence God has given us in creation or with the text.
When I realized that there are two creation stories with different orders and methods of creation (one ending in Genesis 2.4a and the other beginning in Genesis 2.4b), it became very clear to me that those early chapters are not to be taken as literal history.
