Lyna, you only joined two days ago. You need to give it time. Send messages to people also looking for language exchange, a language you both want to learn, or someone who is also looking to learn a language you speak. Send a polite message of introduction about yourself. Try to understand, some people are very busy, already have partners, or may be somewhat inactive on the site these days. But please be patient. Making friends doesn't always happen in a day.
