do i have hocd or am i lesbian?

Hello:(

I am 14 and a girl. I am worried sick that I might be lesbian or bi! It all started when my dad asked me if I was a lesbian and I said no, but felt very anxious when I said no, then I started obsessing over it! I've had this for about 5 months and it is KILLING me:(! For the first couple months I'd check every person I passed to see if I liked them and test different little scenarios in my head to see if I liked them, they made me feel sick and anxious but then my head would tell me that I actualy really liked them. I have liked boys my whole life, and never even thought of girls as more than a friend. But anyways it went away and then one night I slept at my bestfriends house and she said to me let pretend that i'm your boyfriend so we did, and she felt me up and kissed me. I guess I didn't mind it and I don't really remember if I was turned on. All I remember is wanting to stop and have some fun with our other friend who was also at the sleepover, at the time I think it was because I felt really awkward and anxious kissing her but now my 'HOCD' is telling me that it was because I was embarrassed about what my other friend thought. So anyways, when I went home I didn't want to talk to my friend about it at all, I hardly talked to her for about 3 months cus I was really scared to. But this is when the horrible anxiety came back. The past month everything is just out of control. I go through days where I feel totaly straight and normal and just where I love guys, then I go through days of serious anxiety and realy depressed. There are 3 girls who trigger serious anxiety, the one that i kissed, my neighbor, and a girl in my class. Whenever they come near me I have to make an excuse to go somewhere else and it's awful. I can't even let girls touch my feet or sit within a couple centimeters of me. Whenever I feel a happy feeling towards a guy my brain immediatly says that i'm just denying the fact that i'm lesbian or bi. Then sometimes I get a happy feeling towards a girl (or so i think i do) which is immediatly replaced by anxiety,depression, and just needing to get away from everything. Whenever I see lesbians I get very anxious and find it kind of gross, but then my brain tells me that actulaly im really jealous of them. i've had a couple boyfriends, nothing serious though:(! and ever since the HOCD started I get pretty awkward and anxious around guys, even though I never used to. When my sister jokingly calls me gay I also get very anxious. Then whenever I get really happy about liking a guy, my brain tells me yes, but you also like girls, which just gets me super anxious again:'(!There was one night where I completely convinced myself I was bi, and it made me cry my eyes out:(! I told my mom and she said it was just a hormonal thing which would probably pass and even if I was gay she would be fine with it, this made me feel a little better but then i told myself if it;s not hocd then I actualy am gay and it's real, I just need help. I obsess over it 24/7 and without that little kiss with my friend it would be so much easier to tell if it was HOCD or not, because when I think back now my brain tells me I was really turned on by it, bu I really can't remember:'(! I just wanna go back to the normal me, liking guys, and now it feels like I've been hiding the real me my whole life. I used to be the sporty boy crazy girl, and now I feel like some disgusting lesbian:'(!

Please help me:'(
