My dad died last week and now I am the only male in the family.How do I procede?

Okay, this idea that women are not able to manage household by themselves is not true unless they are not themselves earning a living. Your mother is earning(though less) so she will manage the house alright on her own with the pension and some help from your side.

From what you have written, I think your main concern is your sister's future and that is really laudable. But never tell anyone what not to do, because that never works. If your sister wants to become a singer, there is nothing wrong in that. In fact making money out of your hobby is one of the best things in life But tell her that singing is a very competitive field. And it is also a very exploitative field. If she wants to excel at singing then she has to combine that with STEM subjects. For example, there are university courses that teach mathematical music theory. This will give her an advantage in not only understanding music, but also maths and computing. She can then use that knowledge to create her music and songs that will have an edge over others.

Do not force her to become a doctor. Think of the patients too. Here is something to brighten up your mood and explain why: https://www.youtube.com/watch?v=Xh0-x1RFEOY

That apartment is my mother’s not mine. In the end it’s her say. Her friend has a nice empty apartment but she cannot find tenants. My mum says we have already enough problems. That apartment needs renovation with money I do not have. I can dream only now. She says asking for 50euros a month would be too much.

I do not think my family are freeloaders. And I do not want it to get to that that my sister becomes one. She actually is not materialistic but dad was awarding her for good grades, reading books.

Your dad should have achieved financial stability in that age. You are too young to have significant amount of money. It's not your obligation.

I know something about sacrifice (my father sacrificed a lot and in time i also did something similar) so i hope my suggestions are helpful to you.

1) First off, it is your duty to help and look after your Mother/Grandmother/Sister as long as possible. You are all in it together and each have to be clear about their responsibilities and contributions so that your family as a whole is stable. Best case is relatives/friends help out and worst case is you are on your own. The latter is what you need to prepare for.

2) Second, set your Mental Attitudes right. Build up Fortitude and dial down Expectations and Wants drastically. Your mantra should be "a bird in hand is worth two in the bush" until you achieve a financial sweet spot. The immediate future is going to be very difficult and unless and until you "keep it together" things are apt to blowup. Be prepared to do a lot of sacrifices.

3) Third, Financial planning and stability is everything at this stage. You and your Mother absolutely need to keep your jobs and bring in some steady income. Grandma can take care of household chores along with your Sister. No money should be "wasted" on anything frivolous. Everybody should know and be asked to deliver on their specific Responsibilities.

4) Fourth, i foresee your Sister as a source of possible problems in the near future. All of you need to sit down with her and make her realize the precariousness of your current situation and how she needs to "grow up" now. No unnecessary expenses and if possible she too needs to get a job asap and help out the family. Only after you have reached a financial sweet spot should she (and anybody else) be allowed to indulge in their "Dreams".

Good Luck!

1. This is a weird place to post this, Reddit has several subs with a user base much better equipped to handle this.

2. You're having weird feelings because you're grieving.

3. You have a strange perception of the women in your family, as if they are helpless and need looking after.

3.1 That's a lot of pressure to put on yourself, they will be okay, you are not expected to be a white knight riding in to fix everything and support anyone.

3.2 I Guarantee they are not so helpless, 2/3rd of them raised you and have already been supporting your family and your dad.

Sorry for your loss.
