Your example relates to the literal meaning of this statement 'you are looking (a little) lost' - You look as if you cannot find what you are looking for - either a place, a person or a thing. This person might be a tourist, perhaps holding a map, and looking in every direction because they are not sure which way to go. 'Somewhere' does not specifically mean 'WC'. Hope this helps, Rachel.

"are you looking for somewhere -- is there a place you want to find? because you do look like a little lost" -- you look like you don't know where you are

Susan: I think Rachel has given a good summation, but for the sake of clarity, I would like to go through this sentence. SOMEWHERE is not the needed term. A person in a store, looking for SOMETHING is appropriate. Whether it is a Water Closet (Men's Room, or Women's Room, Washing Room, Rest Room, Bathroom are all terms which will serve as a place to relieve one's self) or a product does not matter. SOMETHING is the appropriate subject. Someone saying "You look a little lost" is only trying to be helpful. They can read a face, and see that a person seems to be looking for something. It does not mean that they think you are UPSET. It means that people searching for something, whether casually or in a hurry, have recognizable looks on their face. It does not mean they think you UPSET in the sense of emotional turmoil. It is normal for people to search for something, and equally normal for others to offer friendly assistance, which may not be the norm in your country. Western people are often helpful this way, and are alert to the needs of others. Remember that in Western Countries, where English is the language, speaking to strangers is not out of custom. Speaking to strangers is very common and you should become used to the offers of help from others. It will help if you learn common phrase in response, instead of turning away and feeling awkward. You can say: "I am looking for the .........New Sony Playstation, or Pain Medication, or Ladies Shoes, Cell Phone Chargers, or the Restroom (Water Closet or "Ladies Room"). In English Speaking countries, it will be regarded as a sign of rudeness, if someone speaks to you and you do not answer them or if you turn away. Even if you are so shy or confused, you should learn a useful phrase to answer with, even if it is something very primitive like "No English". A smile would help in such an instance.

When you feel lost means you lost your bearings, your orientation and you don't know where to go.

are you looking for somewhere because you do look like a little lost This sentence is wrong (apart from no punctuation and whatnot)! You look lost. He looks lost. (no "like") "Are you looking for somewhere? (I'm asking) Because you do look a little lost."
