When someone is made unwelcome, it means they are being excluded and not accepted. There are many synonyms to describe this feeling, including ostracized, shunned, rejected, rebuffed, excluded, disdained, alienated, and snubbed. Each of these words can be used to convey the feeling of being unwanted or uninvited in a particular situation. Being made unwelcome can be a painful experience, and it can lead to feelings of isolation and sadness. However, it is important to remember that not everyone will be welcoming or accepting, and it is best to find a community that embraces and appreciates you for who you are.
