Just a homophobia rant

So I'm 17 years old and I've known that I liked girls since I was 12 years old, and recently realized I probably will only ever be with women. Coming to this realization has been really hard for me the past two years, knowing that there is so much hatred and disdain towards us. This past pride month has been really hard for me, I feel like I've just seen more homophobia than usual. I'm tired of being treated like my sexuality is just me exploring, or being in a phase. I feel like I'm never seen as legitimate, especially because women and women's relationships as a whole usually aren't seen as legitimate. I'm sick of people assuming shit about me, just because of my sexuality. I'm sick of feeling like I have to suppress who I am to cater to people that will never understand. I'm sick of blatantly having to lie to my stepdad because he's the only one that would never take me seriously. Thankfully I have a mainly supportive family, but its extremely damming to know that if I ever get married (if I even legally can), many people would not come. I'm sick of overhearing that lesbians are "disappointing", or ugly, or gross. I see beauty that people will never understand, and I really wish that others could. Everytime I hear someone mention a lesbian or anything LGBT I immediately start to panic and my heart rate goes up. But nothing can change hearing your own family member say that he could never accept his kid as a gay or lesbian.
