Hello and welcome to PC!

If you called your mother and asked her why she is shutting you out and how that makes you feel, how would that conversation go? Would communication make this situation better? I always believe in trying.

Trust your gut. If you feel this is from your sisters being against you, you are probably right. But, I wouldn’t say that to your mother because IME that backfires.

I can tell that whatever you did doesn’t warrant your being shut out.
