Nah I live back home and this is not normal especially coming from your own father who suppose to protect and guide you.Sis don't stress out or it will just take a toll on you and no one else. Someone that grew up in the west will always find it difficult in Somalia. There is such a big difference in dhaqan because you weren't raised in Somalia. People back home think diaspora kids are dumb and can be taken advantage off, because of the language barrier, difference in dhaqan and believing that people in the west have lived sheltered lives. I don't think you should take things out of proportion. Your edo and the maid and the other people in the house just ignore what they say. But I would say this...sometimes coming from the west we are bit more quiet and introverted and take things too seriously. Whereas people in Somalia say the maddest things to each other as kaftan(joking) and are loud and social people.
So it's better not take things too sensitively. Like the niece who is joking about the guy getting married to you and you taking him to the west...that's normal kaftan joke in Somalia, hence why your dad laughed when you told him about it with a serious face
. Anyways your dad doesn't hate you or have ill feeling towards you. He's just a typical somali odey who thinks you're a spoilt fish and chips diaspora.
Whilst in your Somalia just try not take anything to heart. Be a bit more friendly, try to eat whatever the other people In the house are eating, go to the suuq with the girls and get out of your comfort zone....enjoy the rest of your holiday with a positive outlook and hopefully everything will turn out good.
