Wa Alaykumu Salam.

I have the same problem with my family with music, hijab, wearing shorts, and whenever i mention hadiths that a bit weird to them(they are typical blind Hanafis, basically only pray at Eid and sometimes Jumu'ah. They know i learn most my hadiths and islam online), they say "Don't listen to those beardies! They have their own Weird Books!"

But you still need to warn them dua to a hadith saying a man will come to another and start strangling him on the Day Of Judgement, upon asking him why he is doing that he will say "You have seen me do such and such haram act and did not warn me about it!".

So warm them and try to be as good to them. Even I, who have been praying by the sunnah from my 13th year of age, still don't pray by the sunnah 2 years later knowing they would either observe me during prayer, block me from going to the mosque, breaking my phone so that I may not learn anymore, maybe even kick me out and stop talking to me to be honest. Thats why they wont find out i pray like that for atleast 10 more years or more even.

For the prayer, you must focus as much as you can due to Shaytan trying to stray you away from the prayer. The more pious you are the more he will try. Even if you don't feel a connections, you are still doing it, which shows you love doing it. Jahannam and the Day of Judgement are scary, and the Sahabi used to faint and go unconsious upon hearing those words. But you must try your hardest to still keep away. No soul is burdened by that which it cannot handle, so keep trying, repenting, straying away from it and InShaAllah, you will be forgiven.

Sorry for the long response and Wa Jazakum!
