Mr. Strawberry, you live in one of the most affluent cities in the world, with virtually every convenience mankind can imagine. Yes, having a car is expensive there. Yes, getting great produce for cheap may require you to transport yourself outside your block or neighborhood. Yes, housing there is incredibly expensive. Yes, traffic is bad.
Nobody has an easy time looking for good healthcare in the US. Call your insurance provider and ask for doctors on your plan, and ask people who live nearby.
Why in the world would you get your hair dyed by an Instagram celebrity? I wouldn't hire Jared Leto to cut my hair just because his looks nice. If you mean a stylist you saw on Instagram, you probably want to read reviews or get references from a stylist if they're going to charge that much. It's also not difficult to take a train to a borough for cheaper, quality services.
Manhattan sucks if you have unrealistic expectations about living there. Downvote me for negativity if you want, but your list seems like entitled whining, and this is honestly ridiculous.
On the other hand, what I would have said sucks about Manhattan are the politics and corruption that stifles the ability for poor people to live there. What sucks are actual food deserts. What sucks is the low-level stop-and-frisk that continues to discriminate against people of color. And, on the lower end of complaints, the deteriorating subway system that still works, but not nearly as well as it used to.
