I'm near-desperately seeking advice from any seasoned/not-so-seasoned, compassionate, professionals:

Sporting Columbia blue [what an unflattering color...], I just got a BA in Architecture and want to eventually go to grad school, but desperately needed at least a year to grow up a little more before returning to school. I'm interning this summer, paidly, with wonderful people, but they can't offer me more than an internship and are actively encouraging me to find other work.

Clarification:
Began pre-med reqs, failed gen. chem [the bravest and among the most painful and futile things I've ever done in my whole life, to date, was show up for a final for a class that I knew I wouldn't pass], and settled on Architecture.
I managed a 3.2 major gpa, as compared to a very low overall partly due to one long nervous breakdown/existential crisis-y train wreck of a sophomore year, among others.

I took historic preservation classes senior year, love lab science [though if you looked on paper you wouldn't know] and am more than competent at it, but taking science courses with pre-meds ruins things. I really, really want to go into conservation/restoration/something of that ilk. I don't think anyone in my department particularly liked me/I wasn't a favorite, but I never received below a b/b+ except for 2 or 3 b-'s, with a b/b+ average in studio.
I was able to do the same amount of work as the graduate students [less maturely and perhaps less polished, but that was more out of laziness than lack of interest or ability], and was definitely capable of equal or better quality in some cases. My senior portfolio was not the best, but was absolutely not the worst/least polished of my bunch.

I've worked every summer since I graduated high school, worked/interned during the last three semesters, and I've gotten each of those jobs without the help of a family member or knowing someone in the office. Everyone has at least told me that I've done good work; the most negative comment I have heard is that I've completed something too slowly, and rarely. I have stayed late, whether or not I would be paid for the time to complete a day's task and I think that if my employers and my professors got together to have a chat I'd get a more even, accurate review than just my transcript.

I'm interested in product design, historic preservation/conservation/restoration, and landscape architecture. Maybe urban design.

What do I do now? How do I make up for time and money I personally think I wasted in college? How do I get there? And will I ever, ever get into grad school? Is there a program I haven't heard of that I should look into?
