<human>: Provide a brief overview of the text.

So both my girlfriend and I are 18 and starting college. We are both 2 years ahead thanks to some dual enrollment. We have been "officially dating" for a year and a half, but have been best friends (read: I had a massive crush on her) since 6th grade, and were more or less together for the last three years. (We waited to date until we were a little older, we felt it was stupid to try to be serious at 15).

As young as we both are, were pretty ahead of the game educationally and for me at least, economically. We would like to get married in ~3 years. I love this girl more than anything and I know she loves me too.

Heres the problem: she is starting med school, and like most med school students her workload and stress level is insane. I expected her to be busy but I was not ready for anything like this. I am committed to this girl but have no idea how to be a good boyfriend with this huge change. I really wish I could have more of her attention but I understand how much she has on her plate. Have any of you Redditors been in my shoes? I would love some advice on how to be a blessing and not a curse for her while shes under so much stress.
<bot>: Would like to keep a happy, healthy relationship with gf, but med school has been more challenging than I thought. What do I do?
