Should I change my name and renounce my nationality?

23M from Egypt dated an American girl she got me on tiktok and after a while she started acting weird and accusing me of being misogynistic, shady, having ulterior motives, mentioning women that get killed tortured and raped in Egypt etc, we broke up, I started using TikTok more and I found women posting about vacationing in Egypt and getting a partner then getting married, all the comments were Egyptian women saying the exact same things my ex used to say, I'm a 100% sure she broke up with me because of those exact type of comments.

I can't get a Visa to any decent country because my country men that are Muslims illegally immigrate and seek asylum claiming to be LGBT or atheists (I'm an atheist btw) then proceed to rape and assault women and attack minorities.

my parents are trying to convert me back to islam and threatening to hurt me so I moved to another place and changed my number and people who publicly claim or insinuate they are secular not even apostates tend to get arrested or assassinated by random muslims.

I can't seek any professional mental health help because the education system here is so utterly fucked

I look more southern European and in the winter I'm really white and also I'm 6 foot so I will look racially ambiguous in most of the EU and north America

I just discovered this "trend" on TikTok that pretty much got my ex to break up with me I feel sick and I've been crying and feeling like shit for a while now, my only chance to actually move out of here with someone I LOVED is gone because my fellow country men and women are assholes beyond belief and too fucked up and self hating.

the plan is to leave to the EU or Canada the US is almost impossible, renounce my nationality and stay there for 5 to 10 years get a new passport with a new western name, if I get in a relationship me being foreigner will show but I'm taking an oath to myself now that I will never ever share my true origin with anyone ever I feel so fuckign ashamed and mad, I genuinely never felt even slightly bothered by what going on with Palestine, this ideology is a cancer I had friends that wanted to go commit massacres in Israel but they were only stopped by the heavily armed borders its a rotten geolocation.

I wish I can erase my identity from my future and hopefully my the future of my kids if I have any.

the last time I went on a date the girl told me she'd kill her future kids if they ever left islam and that she hates dogs so much (islam actually encourages the killing of specific types of dogs and prohibits owning them unless its for safety or hunting), people here force dogs to stay outside leashed in the cold winters and the scorching hot summers.

anyway to the point of the post, any advice on how I can do that (change my identity) if I change my name I will have to change my entire name right? or can I just discard it? is it even possible to have just a first name? how do people do these things? assuming I actually managed to immigrate and leave the country which I WILL.
