As a Swiss citizen you have the right to live and work in Switzerland (and also in the EU for that matter). Your challenge will be to integrate sufficiently by being able to communicate in a Swiss language so that you can support yourself after arriving. Here are some thoughts on this:
1) Take an integration course, including a German language course, for a year. Apply for apprenticeships while studying. (See translated article below).
2) Get a job as an au pair for a year with a German-speaking family to help you master the language and begin applying for apprenticeships.
3) Begin applying directly for an apprenticeship starting summer 2016 while you are taking your current German language course.
Below is a translated newspaper article about how Canton Vaud place young people between 19 and 25 years old in apprenticeships: https://translate.google.de/translat...309&edit-text=
For more information on an integration course, try googling on "integrationskurs". This is an example for Canton Zurich. Use Google Translate to read in English: https://www.stadt-zuerich.ch/ssd/de/...ion/Login.html
