It might not be your fault, since Trust Wallet can be easily hacked but it is seems like you know the right ways of saving your funds but I don't know why still stick with Trust Wallet but hope you are going for a more better wallet or at least a good hardware wallet like Trezor.
Hope your Mom gets better soon, the is your strength, I see you already did made a post in their ANN thread base on MusaMohamed which will get to their notice faster
I guess I'll need to move my bitcoin again, didn't know that Trust Wallet is that easy to bypass that they can just easily take away the funds in someone's wallet that easy? Kind of ironic that, you name your product as Trust Wallet but then you as a hodler can't trust to put your funds in there, I guess the plan to move it all to a safer Electrum wallet is going to be a priority to me now, prevention is better than cure.
OH but you been on this forum since 2016 and you still store all/some of your Bitcoin on Trust Wallet, truly this is surprising and I would love to know how you even cope during mempool congestion because Trust Wallet has many limited features aside from it low security and charging exceeding fee. In case you are still using it for altcoins, I will advise you move to MetaMask or any other open source good altcoins wallet
