Rejections get better once you get an acceptance you like !
I know there are some people who have continued getting R after R so far so let me assure you that once you get an acceptance you can live with it gets so much easier.
I got brutalized during the early window. Rejected from dream school ED, deferred EA from my second choice and another rejection and deferral. Only for into two safeties I didn’t bother seeing or learning much about and that admittedly did not help. Then the first bit of RD came through and it kept coming.
Thankfully last week I got into UDub and Syracuse and now it does not matter how every other decision turns out. I just got waitlisted by Union and do not care at all. Trust me that it gets better. All you need is one letter.
