I have a similar path, i got a math degree BS and a marketing master, yet i can't find any job, i'm 26M, my mother tell me to get a sell job but if she knew how weird is it as a stutter to guide a client.. anyway i have a vert similar life to yours, all i can tell you is that you can maintain relationship by action and not talking, small ones but it matter, i'm very close to my siblings and mom, cooking with them and for them, ask them to watch anime or drama.. it's always nice to have a bond, everything else i cannot get since i'm slighty below average looking and not tall.
