First solo travel and completely excluded myself from society

Hi, 19m, landed in hanoi yesterday, did not do much as i was mega jet lagged and just wanted to sleep. Today was supposed to be different, acquired 8 and a half hours sleep the night prior, this was supposed to be THE introduction day to vietnam. I left the apartment 3 times, 1 to get food, 2 to get a plug for my phone cable and 3 due to the fact that i stared at myself in the mirror for 10 minutes telling myself to man up. What do i do in this situation, i have friends coming to hanoi in 2 weeks, how do i do the next 2 weeks and just not exclude myself from society as i have worked hard to be able to do this trip. Thankyou for reading

Edit: just wanna say thankyou to everyone replying to this, all of you are super helpful
