It is nice to see that someone feels so passionately about providing care for defenseless animals, and I fully support you on this. And if you get this job to save 1-2, or even a few more of these animals, you will probably succeed. However, if you are in need of a job, but also want to disregard the policies & procedures of the establishment, you will probably end up losing your job. So you need to think this part through.

Also, my bf is a Video Game Design student. He has thought about dropping out of the uni because it's expensive, he does not see eye to eye with some teachers, etc. But we researched the job market in his field (which is similar to yours) and realized that a degree is a big asset in having as many choices as possible in regards to which company to work for. You can get a job without a degree, but the direction in which these industries are moving will require degrees from candidates in the near future. In addition, I have found that knowledge is one of the most powerful weapons available to all of us. You could change many, many things with a strong will such as yours and knowledge to back it up.

I understand about your condition (or possible condition), and the best you can do for yourself is to try to be as disciplined in all aspects of your life as possible. You will feel much more in control, and will actually have much more control if you get yourself organized and have a routine (this does not mean you cannot have fun. There is always time for that).

You are young and have your whole life ahead of you. You can choose to make the best of that (& not compromise what is important to you, such as ensuring the welfare of animals), or you can easily throw it all away. Ultimately, is up to you. But if you do appreciate the people that listen to what you have to say (like everyone here has done), then cherish that. If we were not concerned about what you have to say and what is going on in your life, then we would just not respond.
