Dwindling Days

I have been getting stressed for the past two days and i don't know why? It is not like my life isn't easy enough, i don't work and i live in a chill town but the fact that I have less than 5 months in Australia that is worrying me, and the fact that I don't know what will I do after I leave this place is really affecting my moods these two days. I can't get it, my life seems to be getting to where I want it and was crying for it. I am having fun and getting to know this friend of mine that I am living with but something is not right, I don't know what that is, I am uneasy all the times and I just don't know, somehow I can't relax. There seems to be not enough time to do a lot of things and it's been like this for the past 3 weeks. We ended up being the cleaners of the house rather than living it. That is killing the fun out of here and the fact that I am not working is also taking its toll on me. I can't do anything fun, I can't spend too much money because I need the money for my visa to Europe, the USA and New Zealand, because of these reasons I have been trying to live a very cheap life, is it worth it, I don't know. I am worried that I won't be getting my visas but also I am really missing the fun of being in Australia, travelling and enjoying my life. S
