I understand. Apart from sharing a apartment with 9 - 12 other people.

But you have to understand, this doesn't necessarily mean we don't have fun. When I was in Bay Area, I knew a dozen ways to save up money while having fun. I didn't own a car, because the company gave me a VTA pass. I knew how to cheaply explore places around Sunnyvale, CA. I knew how to reach SFO, and explore places there for cheap. Where you could eat cheap. This also means, investing in quality and frugal stuff. A good $14 for jeans pants at costco(bought from a friend's costco card of course), buy a pair, and buy a pair of t-shirts. Then may be timberland shoes. Invest in a good jacket. Now your clothing is covered for years. A bag of basmati rice costs $15, and lasts at least 2 - 3 months, invest in a good rice cooker and making curry with veggies easy by buying produce at local farmers market. Meat is kind of cheap in US too. Sometimes you just skip meals(think of intermittent fasting as a side effect). Also you can buy a room heater for around the same price at Target. There are lots Chinese/Mexican barber shops around Sunnyvale/Santa Clara that give $8-$10 haircuts. I knew to scavenge through mail boxes, to pick up coupons. Then of course one kid gave me a whole coupon bunch for lyft, and uber eats and eat for free for long. etc etc.

I took good care of my health, so only once did I have to go to the doctor, and I didn't even pay a single dollar, they just asked me to continue taking TUMS.

Is it hard, yes. I mean I was once caught in a thunderstorm and it was too cold to tolerate, and I once missed the last bus back home. Could have taken Uber but decided to save $3 and walked 4 miles in dark and cold, missed because I had to pick up free food at office so the my back pack was heavy. I even at a point could hear my own footsteps which freaked me out real bad, it felt numb walking in the cold. Then of course you have to wake up at 5 in the morning, because you want to take the 7:15 bus as the breakfast is free at office. Its cold that early in the morning, I had tons of janitorial staff as friends because I would travel with them in the VTA and again meet them at office. I remember it almost feels like the cold seeping into your very bones. One day I relocated to a new place and I was sleeping in the hall, the room heater broke down- It felt like my toes would fall off. It was really really cold.

Then there's tons of time and self reflection you get in that much minimalism, loneliness and it kind of touches your soul to its core.

Then you also save a lot of money you can send back home, that in the hopes when you run out of visa time and eventually return, you will have some money to invest and make something out of it. Did it take a toll yes. I'd be barking mad to try all this again. But I don't regret it for a minute. I got a chance which only one in millions get, and I made most out of it. I learned tons from smart people, worked and pushed my self to the extremes I gave everything I had in me. I would always make it a point to visit universities and companies to get a idea of the scale and ambition of the US civilization. I have immense admiration and respect for the American people, and I am always thankful for the opportunity.
