Intrusive Thoughts.

I'm not diganosed wirh anything but apparently I have OCD symptoms according to Google it started a month ago I was playing a game with my best friend and it was a new game we were playing and I loved it and all of a sudden I got butterflies in my stomach and I looked up why and it said love but yk ofc my brain is gonna the other option which is excitement instead I focus on the love part and I start getting thoughts that I might be gay for that happening and it was a horrible for the first week I thought about it multiple times a day and was very stressed! After about 2 weeks though and research I figured out how to control it and I was fine UNTIL about 2 weeks after that I started getting worried about random things one was the fear of having OCD and matching with the symptoms and it messing up my life another one was paying more attention to my blinking and hearing the normal and other smaller and more manageable thoughts like what if I was a serial killer? What if I was a pedophile what if I was gay? And etc. And I have been struggling with the what if I was gay again because I asked a dude for help and our stories sounded similar and he came out as gay the thing is my mind started thinking what if I was gay just in denial or if we were the same and I was gonna turn out gay! Also the fear of having ocd I had which I was just terrified of having it and it messing up my life and I have been paying more attention to my blinking and hearing! I also started like making sure I liked shorts to make sure I can view them at any time in case I forget which is annoying and makes me avoid *** and I don't know what has been happening I was a always happy person and never had any mental health issues now my life is miserable when these thoughts pop up and I don't want to tell my mom yet about it so if you guys please could give me some tips or some good therapy apps it would be much appreciated!
