It's understandable why you feel this way and may Allah reward your intention. Aameen.
Do realize though, that iman is a treasure. It is something that will decide whether we go to hell or heaven. It is for this reason, that Prophet Sallalahu Alaihe Wassalam told us to flee from dajjal. He will mislead and end up nullifying a person's iman, even though that person will go to him thinking he has strong enough iman to not be taken in by dajjal.
Dajjal will be an immense test for the believers. Some hardships can also end up being severe enough to cause a person's iman to be in danger.
You seem kind of young so perhaps you don't realise the true nature of what you are asking upon yourself. You may think of hardships as perhaps temporary things, e.g. your mum or dad dying and then you go on with your life after 'showing patience'. In fact, Allah knows you better than you know yourself. Since you feel the death of your parents will not affect you that much, then your request for hardship from Allah will probably come in other forms that will in fact cause you some kind of suffering.
Iman fluctuates. This is a fact that cannot be denied. If it remained strong all the time, we would be shaking hands with the angels. So, it is silly to ask for hardship while you may be feeling strong right now. Come later, when your iman feels lower and you are being severely test, who is to say you will remain patient enough?
Imagine tomorrow your hand or leg gets chopped off and you have to live the rest of your life without the use of your limb. Or you get given a long term illness that debilitates you for life. Or you get thrown into jail for many years where you get beaten by all the other inmates on a regular occasion or you marry someone you love and she ends up having an affair which you find out years after you have married her and have had kids with her. Etc. There are many such evil fates that can happen to you. Point is, it is easy to assume when you have hard temporary hardship that you feel you can be strong enough and patient enough to handle but when Allah really tests a person for years on end without an end in sight? That is when you need a rock solid connection with Allah otherwise you will lose all hope in Allah's help and mercy and even end up losing your faith in him.
I can't fix nothing with my mom that's impossible she literally hates everyone but hide
Make no mistake about it, the biggest strength in those times of hardship will be your connection with Allah and your firm belief in him. When you make dua, you have to believe it will be accepted and you have to have a positive belief that all things are under his control and he can do anything. In fact, you are not there yet. You already mentioned that you have a problem with your mother but feel that for her to change is impossible. Really? How can it be impossible when Allah has everything under his control? Don't you have faith in your own dua and Allah's ability? If that is the case now, how will you possibly face other extreme hardships and come out with your iman in tact?
Yeah, no. Don't do it. Ask Allah for goodness and patience and try to develop a convinced connection and belief in him.
