I Need Help

I'm having a gender Identity crisis. I think I'm bisexual but at the same time I'm not?? I liked both a man and a woman before but It doesn't feel right when I call myself bisexual ?

I'm scared to label myself as part of the lgbtq+ community because maybe I'm actually just a straight ally who's just doing it for attention /although I've never said it to anybody irl/

I think I'll fall for someone regardless of their gender as long I like them, I like them but maybe it's just my thinking or morals?? But I do plan to just die by myself and not marry someone so yeah

So this will probably be long so please bear with me. Actually, I think I'm living behind a mask and I no longer recognize myself. I mean ever since I can remember Ive always acted towards people the way I know that will please them. Its been so long that I think Im forgetting what I really am. Some of my friends even describe me as someone like this and that but I dont remember being what they describe me as. Its like they are talking about a whole different person. I know I should stop putting a mask and just be myself but at this point I kinda dont know who is "myself". That its actually taking a toll on my mental health .
