Ever wonder why you suddenly suck at the game?

hear me out I'm not some god like shroud or anything I'd say im fairly decent, I have 300 kills, 13 wins, 50 hours into the game and all and I'd say I'm not half bad, I play nearly all day since I downloaded it last week, so before you tell me something like "you just suck at this game go back to fortnite dumb kid" look at my stats first, the names Flaire1775 HMU if u want to play :3 (ASIA). I've just noticed this tonight but as the name says I suddenly suck BALLS at the game, a moment ago I was able to handle a 1v1, a squad fight, hell I was able to handle a squad on my own, and when a few games later I've suddenly died instantly to a gun, I got * in the * by a HEMLOK user!! a freaking HEMLOK!! while I was fully kitted no less (lvl 3 armor and a fully kitted spitfire), next game I got my * handed to by a squad with barely enough gear while my squad got destroyed and they were lower levels as well ( no hate on you guys I was a noob at first but you gotta admit the distance of the skill between a lvl 3 lifeline with 2 kills versus a level 32 Mirage with 147 kills on record on him alone). I mean as I said I don't suck * at the game im fairly decent, if you say its my squad I get teamed up with people way better than me so thats a no, * gear? ofcourse not I use a peacekeeper and the R-301 mostly and I always choose my fights, just all around * at the game? see above, better enemies? well, maybe but sometimes like the situation above thats not the case, Bad luck? Yeah sure, just tired? dude I was pumped all day playing this game and I also do take rests after a win or a good game. Idk why this happened to me and I'm sick of it, maybe the games been out so long that people just got better but I don't know I was playing decently this afternoon, does RESPAWN have a system that  puts you in to the sweaty tryhard server of * pubstompers when they notice you having good kills or something? or maybe because the adults play at night and all so more skilled players are awake, or I leveled up and get matched with the same people, I love this game, It's the one I've been having fun the most lately, It keeps me distracted from my depression and all that jazz, and to not have fun with it anymore ain't gonna cut it

any advice you would give to a fellow fan of this spectacular game? I would appreciate the advice and the discussion
