Hey yo, what up!
Here is something I can suggest you try, since you are worried with that 'alone' feeling. Try a little thought experiment, at least it might keep you amused for a little while.
Think about something (but don't say it out aloud) , and pay attention to how you are thinking about it. Then, go about your day normally (go outside and do stuffs or whatever) , but then also pay attention to what you see or what happens, both in real life and online.
You might start to wonder... was that just a simple coincidence, or maybe you are strangely wierdly not so alone afterall...
Oh, and about your mum and family, only real thing I can suggest is.... its cool that you are discussing with them and everything, and you are standing your own ground and opinion and stuffs, but maybe try not to let it get too heated too much, and end up yelling and arguing, or you might have more to reconsile later. Maybe she still is as 'based' as you think and remember, but at some point, you are you, and maybe just maybe you will have your own 'changing guard' thing to figure out. Maybe.... there is a hidden option, that allows you to not-jab and she/family will still be happy and not feel endangered.
But if you really reeeeely wanna be "oh woe is meee so alone, what will Q say right now..." , then pay attention to what you see around you, might just maybe get a funky hint to 'randomly' go look up some certain Qposts numbers.
Edit: added summary... i dunno man... we all got our own thing, and I'm sure you got yours too... just maybe try to not fight each other or yourselves too much, coz then gotta reconcile later and stuffs.
