I am stuck. I need help really badly.I thought the anti-venom was supposed to be in the upstairs bathroom in the medicine cabinet but everytime I open the cabinet.The package is empty. I have tried to get it before and after the snake bite but its not there. It says its empty. Is this a glitch in the game

It might automatically placed in inventory. I vaguely remember that happening on a replay of mine. It might not be a familiar looking item. Also check if you might have placed in storage cabinet.

I tried replaying the part where Victoria first arrives at the house. I went to the bathroom on the second floor. I opened the medicine cabinet but the anti-venom is still empty.

Heavenm

I sent you a saved game with Vic in bathroom. Please check about the anti venim.
