Hi Eman,
your former visit in Germany doesn't generally affect your chances to be accepted as an asylum seeker. See accurate informations about German asylum law here: ****://bit.ly/2chLgMx (follow the menu on the left on this site for details).
During the asylum process you will very likely have to explain, why things have changed so dramatically in your country, that you were obliged to leave.
Please read the basic informations about the asylum procedure I gave you as a PDF elsewhere (https://***.wefugees.de/k/questions/1654)
Kind regards, Jan
