Can I say "attack" instead of "strike"? Or do they have different connotations?
They do have slightly different connotations! "Strike" is a single action or hit, whereas an "attack" could be more than one hit, and it could last longer. One can "strike" someone while "attacking" them. However, in this context, it would be fine to use "attack" instead of "strike", as they both indicate the beginning of a fight or attack. Ex: Are you ready? Attack! Ex: Just one more strike, and he'd be unconscious. Ex: Did you see the news? Someone was attacked last night. They had to go to the hospital. Ex: I was struck on the arm during a fight. Ex: Those bugs could attack at any moment. = Those bugs could strike at any moment.

Is the joke of toilet in this sentence often used?
No, not really. This is just an expression. She said "I'm going to just flush myself down the toilet" because she is extremely embarrassed that she thought Chandler was gay. "I could just die" is a more common expression for being embarrassed. English speakers may also use "I made a fool of myself" or some may even use "that will be egg on my face." These both refer to being embarrassed about something, but there are many kinds of expressions that are used.
