Dating site losah, need advice?

I revamped my dating profile. Before, I posted a sincere introduction about myself, and now I turned it into a mean spirited one. I guess it's working bc females are taking notice and messaging me. �I don't want to post a cheery profile bc no one pays attention to it. It's so disappointing when I message 40 girls within a yr, and I get no effin response. I will get a response only if I try to befriend them first. I seriously think the lesbians are racially selective or overly shallow. I don't know what to do. :(
