At the risk of sounding like you should be lax, which is not what I'm saying, but I think you are too hard on yourself. Continue in path you're in. Some of the things you say, (like the flood and evolution) I also struggled with as well and found myself not in agreement with my own confession father (and that's coming from a cradle Orthodox).
Pray and take your time:
I am certain that you can correct me on certain points, but I would prefer to learn slowly so that I will better absorb material.
And if there's any questions, many here are willing to help, but your spiritual adviser is your most important source.
PS Now in Twitter limit or less, describe how "I can't believe it's not butter" not butter.
