Dear @Mighty Deutsch,
Thank you for reaching out to the Wefugees community and sorry for the wait!
As a working Master's student myself, I can completely understand that it can be extremely stressful and time-consuming, or that you feel like it slows down your studies.
Have you looked into finding a 10-hour job? That could make it easier to handle both your studies and support yourself financially. Depending where you study, universities usually have job listings or job search portals where you could have a look. There are also student support services that you can ask for help.
The following thread from our platform should answer your question regarding asylum:
Can I apply for asylum or refugee status through a student visa ?
And this thread should provide you with a few helpful suggestions regarding staying in Germany by our asylum law expert Nilab:
Can I apply as a refugee or asylum, if i have a student visa from france?
Regarding your last question, here is a lot of information on joining your spouse with a permanent residence permit in Sweden: https://www.migrationsverket.se/English/Private-individuals/Moving-to-someone-in-Sweden/Spouse-registered-partner-or-cohabiting-partner.html
I hope this information helps! Feel free to reach out to us again if you have any more questions :-)
