Will I stay Single forever I'm seriously depressed ugly 16 yr old female?

I've been depressed about this for ages now. Allright so I'm not the best looking person around. I wear gles, I have a slightly nasal voice, i have nose freckles, pale skin and im what people consider a ''ginger'' however i dye my hair black. ive always been lonely all the way through elementary & mid school, now in highschool, everyday i watch couples walk around with each other after cl kissing having the time of their lives, a majority of these are 14 to 15 yrs old. I however have never had my first kiss, ive never been in a relationship, and nobody has ever asked me out. i have a close friend, not attractive and kinda chubby but we get along sorta well and some other kid in my cl knew he had a slighttt crush on me and came up and said to him ''come on dude...you can do better then that'' that really made me feel bad. im the type of girl that has interests most girls would never think about like i answer questions in science cl i like computers & techy stuff ect..the only people i could ever remotely get along with was the nerds (i have a major thing for intelligent boys), like i REALLY loved this one nerdy boy he was soo cute really smart sweet and shy it was ADORABLE i went four months being in love with him even if he didnt know it i helped him with stuff i was sweet to him i tried to ask him out last week and he said he hated me and a relationship was ''never gonna happen'' and got rejected now hes dating this dumb, fat, bitchy preppy girl who doesn't know a plank of wood from a nail. today they were both making out at the end of the day and i almost cried but didnt. i really loved him but i cant help but feel angry... his friends just tease me spread rumors and make me feel worse, even for a simple friendship theyll reject me no matter how similar our interests are and mock me again. the mrs populars spread rumours about me, and i sorta hang out with the ''reject/loser'' group or on an empty table at lunch. i was once attracted to this hot popular guy but he did exactly the same he said i was ''not his type'' that really hurt too. im really shy & very sensitive now im depressed im even shyer. ive been rejected like this many times back in elementary and i thought id have some luck at my age but the heartbreak is really hurting me. it hurts to see the boys i was once attracted to go out with a bunch of dumb sluts they dont deserve. even if they rejected me in the past i still love them but that makes the heartbreak even worse. i know im ugly but surely i cant be that ugly? im not obnoxious, i have a good sense of humour, im thin, im smart i dont wear tons of makeup and i dont dress like a slut, why am i so repulsive to boys? will i honestly stay single forever i see people getting married at my age & i havent even had my first kiss yet! im really upset about this please help idk what to do anymore how can i cope with heartbreak? :(
