Some rules on how to address problems

It does not help anyone, if you try an hide something that is disturbing you. You will have to live with it for quite some time, and the others will definitely notice that you are unhappy. Especially kids realize this very quickly, so eventually everyone will be annoyed. So once you recognize something you feel needs change, simply address it with your host parents.

Of course, once there is something you need to change, you would love to talk about it as quickly as possible. Nevertheless, it is better to wait until the kids are in bed or simply in a different room and you are alone with your host mum/dad. Also, try to make sure they are not just rushing somewhere or need to get to work urgently. Choose a moment, when you both have a bit of time, noone is occupied by the kids and you can speak freely.

Okay, I surely don't want to you practice this like a presentation or so. Simply be aware of what disturbs you (e.g. too much working hours). Then maybe have some examples on hand, or a sheet where you wrote things down (e.g. the number of hours worked every day) to support your argument. This makes sure you will not suddenly forget about your main points because you feel nervous and your host parents much better understand what is going on and you can find the best solution together.

If there is something you want to change (e.g. never enough vegetables available for cooking), then think of ways how to solve this in advance. This way your host parents see that you have thought about it and don't just complain, and you will get to a conclusion much quicker. For example, you could introduce a shopping list that everyone can add things to, or you get a specific amount of money from your host parents to buy vegetables once these are out when you are one the go anyway.

I know how hard it is in such a situation. These are the people you live with, but still they are your bosses, and you want them to be happy, but also you want ot be happy, you don't acutally want to occupy their time, but this is important for you. It is tricky to balance everything out. Some topivce might be more emotional than others, and it is absolutely okay to show what you are feeling. Still, try to stay calm. Sometimes in these situations, we suddenly mix our home sickness or disappointment about someting else with what is going on here. Crying and getting loud does not constructively help in such a situation.
