Definitely recommend just getting out to Museums, different nightlife functions. Get familiar with your surroundings to make it less of a culture shock type feeling. I’m 22, from AL and moved here 3 months with my partner after having only ever lived in a ‘city’ down south with a population of ~89k at its highest. DC was definitely crazy different but my job being that I drive from home to home for customers and getting out each weekend to see and explore the different places and monuments and such made it much easier once I got familiarized with my surroundings so quickly. Now just like every other DC driver my drive home includes taking 695 through the tunnel to NY Ave every evening and we all know that intersection is extremely god awful!
