Supposing this was a deception from Satan, even then, why do you worry so much? After all, you have done nothing wrong. If you believe in Satan, I assume you believe in God too. If Satan is deceiving you now then what's to say that he wasn't deceiving you when your loved ones were alive !

In my opinion, there can be nothing beyond God (if you believe in God) and if Satan is able to lure you away from God through no fault of your own, then why would you believe in God in the first place. I believe that energies such as Satan only reflect your own fears and if you place your trust in positive, the outcome will manifest as positive. I hope this makes sense. If God was testing your faith (with the help of Satan) but unwilling to forgive, then such a God would be unworthy of being God by very definition of God. I wish you well :-).
