I am too fine when I am not talking to someone . My family keep saying to make friends but I don't feel the need to. They have been very upset about this. What to tell them?

I cam back from college recently after my latest sem was finished. I rarely talk to people there. Got like one person who I talk to there and I think it is enough. Came back to home and i have been basically living in it for 15 days. Just walking out of it if I need food from the kitchen or anything else. Never had friends in high school too . I kinda feel too comfortable laying in my bed and doing nothing. And go without taking to my family for a long period of time even though we live in the samw house. Rhwy have criticizing me for being this way even though I have explained them many times. They kind of hate me since high school for being this day. What to tell them or do??
