Feeling lonely in an Islamic household.

I'm an introvert and have often isolated myself from my family for years. Now I want to rekindle that bond, but it's hard. They all laugh and have their inside jokes, which I don't understand, as well as, not knowing how to approach them due to the culture (I'm Pakistani from the UK) As a guy, it's difficult to bring it up with the fear of being knocked down for being too emotional etc. I'd like to hear advice from people who were in similar situations and how you managed to make your family notice you again.
