I am so upset.. what the hell is this?

I applied to a job at a Language training company as a Translation coordinator. I passed the first interview and then they invited me back for a day in their office as a second interview. I thought my experience and ability is what they are looking for and I am likely to get this job. However, when in the second interview, they brought up the concern of applying and paying for my work permit. My heart sank....
Then today I got this e-mail, I really wanted to say "Wale Fucking la di da!"

I've told them I need the company to apply work permit for me at the first interview, if they do mind, why ask me to go again? If they think I am not up to the par, why kept telling me I've been great at the tasks they set me to do?! Just tell me what I can improve but not pretending that my performance is impressive.

Can somebody told me how to think Positively in this situation. Fuck... this is the worst 30 Birthday present I got.
