Is it normal that i'm really frustrated with my mom about this?

In the meantime, you could find someone mature you can talk to/vent to. A friend or neighbor or counselor. If you're religious or looking for something more in your life then it could be a Rabbi, Pastor, Priest, Priestess, nun, fellow believer of ______, etc etc. Or you could find someone right here online. Anyone who can empathize and give you positive encouragement. Whoever you consider a good influence on you. But please, don't talk to someone online then agree to meet them :P :P :P lol

It is completely normal. You are a human being and by default, have times when you want personal space.
I am assuming you are young. The best advice anyone can really give you is to just try your best to reign in your emotions and put up with what she's doing. She is being too controlling, she is encroaching on your personal space and rights as a human, and she doesn't sound super nice to you. BUT.... you are stuck there so you might as well not put up a fight since that's only going to make your situation worse, not better. She sounds very similar to the way my mother used to be. Depending on her age and health, she could be going through a lot of hormonal issues that are making her feel crazy or up and down all the time. Hormones make people irrational in such a way that you can't even point it out to them so be careful of that.
Something else that might help, is voluntarily share a ton about your life. It doesn't even have to be personal but by sharing so much, it might seem like you're being more open and sharing personal things.
After a few months of doing exactly as she asks of you and volunteering information, try talking to a school counselor about how to approach your mother. She should be a bit more tolerant of you when she sees how exactly you've been following her every instruction and this leaves the perfect opportunity to get her in the best mood possible for talking to but only if you think it might turn out ok. The reason I say speak to a school counselor is because they can give you pointers on how to speak to an adult without making them feel like you're being a smart ass, rebelling, trying to hide something, or having any kind of attitude. There are adults out there who can help you with that but it might be awkward for a teacher if you try to put them in that position.
The most important thing during any discussion and any other situation with your mother is to keep a level head. I know it's hard when someone is being unfair and they're not treating you the way in which you deserve, with respect and kindness etc. But losing your cool, crying too much, throwing a tantrum, arguing/yelling, cussing, all of that will get you nowhere good and will only serve to make your life worse and prove what she thinks is her point in her own head.
Eventually, you won't HAVE to be there in anymore. You'll be an adult and out of school and you can have a real heart to heart with her about how you've felt. Try not to play the guilt trip card, it's honesty that you want. Maybe you'll find out things you didn't know. Maybe when you're older, you'll realize your mother has a lot of shortcomings or mental issues. Maybe you're mother with have a change of heart as she gets older. She's a person too. So just like you've grown over the years, she, too, can grow. Who knows? You may some day get the treatment from her that you deserve.
You can't change people but you can give them the room to change. As hurtful and mean as she's being, she's probably doing the best she can as of right now in her life. It takes a strong person to go outside of themselves and see that and even feel empathy for someone treating them badly. You should feel sorry for people who can't and for people who get set in mean ways.
Considering you've already been through one bad time with her and worked through it emotionally/mentally, you're clearly already strong enough person. You can do this. If you know you're doing nothing wrong, then hold onto that through all of it and bite your tongue until a time when it can actually serve you well to say something. Good luck!!!

your mom says hello also

just give her the dick

"I didn't lie or anything."

But you are hiding stuff in your phone. If it's really nothing wrong just show the stuff. That may be setting alarms off in her head. I'd suggest to just submit to what she wants but slowly not listen to her on small things. Or a big fight with her may change a lot of things.

She's too controlling imo.
