But I won't burn my tokens because there are my mom, my uncle and my sister counting on me, and I hope I can change the life of more people, if I even can change the life of my mom and myself; which is being hard. My brain bugged now to think more so I'll try to focus back on outbursting by building this heresy that no one of these machist transphobe beared professional programmers have thought of. I know Im writing like in 2019 and this is a backstep, but my brain really bugged today, my rare peace of mind from a whole month has been partly broken today. My mom is bipolar, and about Hare I don't want to judge while irritated."
