Seeking guidance scholarship disappointed

Hey, everyone. I am a bachelor student who was kinda hoping to get a scholarship to Hungary for my master's, but I kinda feel like I did a very shitty interview, so most likely I won't be accepted. I am in a very dark place, feeling shitty about myself, and I can't do anything since that interview. I feel like I have wasted the biggest opportunity of my life. I wanna know if there are any other possible scholarships for Tunisians. I am 21 yo, and my marks are pretty decent. Also, what are the cheapest countries to study?
