Question of my uality?

ok iv always been more then alittle bit confused with wither im actually bi or just lez or straight idk y but im just not sure. but does this situation prove something? ok so i broke up with my ex girlfriend but we are still friends and we even did stuff ual stuff when we hung out the day after we were at a someones house and she got drunk and i was next to her and she started making out with another girl i got really upset and had a panic attack and started crying does that prove that i actually do like girls like that and not just ually??
