Getting Egyptian citizenship as a foreigner who spent his whole life in Egypt

Hello!

I'm a 25 year old Russian male citizen who has been living in Egypt with Russian mom and Egyptian stepdad since I was 7 years old. I was eventually enrolled in an Al-Azhar school and was getting a yearly educational visa. This year I just graduated from Al-Azhar university and won't be able to get visa the way I was getting it for the past 16 years.

My stepdad's lawyer told him long time ago that one can apply for an Egyptian citizenship if they spend 15 years in the country, but well, apparently that was a big ass lie.

I know that there's an easy way to get yearly visa through my mom, as she's married to an Egyptian citizen, however, I won't really be able to officially work anywhere with that kind of visa. And also if my mom passes away (لا قدّر الله) I won't have any legal rights to stay here I assume.

So my question is, is there really absolutely no way of getting Egyptian citizenship except for big investments and marriage? (these are the two only ways I found online). And how do so said "work permits" work? Is it only companies that grant them? Or is there a certain paper work one can go through to be able to legally work?

I've been living here for the most part of my life, and now that I graduated instead of feeling like I'm moving onto the next chapter of my life, I feel like I'm doomed and really don't know what to do.
