YES, I'M AN IDIOT: VISA HAVE BEEN EXPIRED FOR 3 MONTHS. IS WHERE ANY ABILITY TO AVOID THE BAN? (EU)

Hi fellows,

Im Monika, from European Union country. Im seriously sinking in huge sh*t.

My visa is expired for little bit more than 3 months. But the sadness gonna come with the knowledge, that I figured out this just a few days ago.

Situation was quite complicated: I came with tourist L here, went to Macao to make an extension. Instead of extension for tourist L of 90 days, Macao office gave me.. 3 days. Now I know for sure - it was their mistake, 'cause I applied for the 90 days, and, by the way, have payed for the same duration as well. Well, I dumb enough, can't deny - it's my fault I didn't check my new "extended" one, after I withdrew it. Anyway, I was living at my bf apartment, without any worries, till I have figure out - I'm here illegally.

I'm gonna pay penalty for sure. 10 000¥ I even want this, 'cause I hate myself for such as huge un responsability.

BUT: all my life is here: my friends, my ambitious; honestly, I have planed to study from his September, but now, I'm just absolutely confused and shocked - what I suppose to do now??? I just want to be even for 80 % sure, I will be able to come back. Is it possible to avoid the ban? Guys, seriously, I MUST come back to this country, 'cause I badly felt in love with China.

What to do now? Where to go (currently, I'm in Beijing) For Whom to complain? Maybe You know somebody with the same story?? Damn, I can't sleep 3 days already, Im seriously going crazy.

PLEASE GIVE ME ANY ADVICE!!
GOD BLESS YOU!
