I screwed up my friend really bad, what to do ?

Hey there, great community of SG

I don't really know how did this happen or what should i do xD , but here's the story in full :

Last Steam Summer Sale, i was normally talking to my semi-gamer friend (he hadn't played games since god knows when) about how awesome steam sales are and that games get huge discounts. An idea sparked in his mind, he wanted to invest, he had some money saved up for his college spendings and he needed an extra 50-100$ or so. i tried to tell him it's not a brilliant idea given that there's no official steam market for copies, but he did manage to convince me ... i got carried away seeing all the cool trades that happen in steamtrades or other websites ... so i agreed on ME taking charge of selling the games since i have more experience than him ..

i never was so wrong in my entire life :'D. Bottom line is and to make this short ... i now have games on my steam library and zero idea on where or how do i sell those, i tried steamtrades but no one wanted to buy because of my low reputation (have only made 4 trades ever so i don't expect people to trust me), and i've tried multiple other ways and sites but all of them failed ..

tl;dr , i screwed him up really badly, i don't even talk to him anymore and keep avoiding him.. he's my best friend and i feel so shameful i did that to him, it's true that it was his idea but i encouraged him more and it's all my fault...

so yeah , i got response from other friends to keep few copies for them , but the rest i'm willing to sell all of them for 200$ (almost no profit at all) so if anyone is interested in charity (as in buying cheap games to giveaway i guess) or in these games i'll leave a list in the first comment, this isn't a post about me wanting to trade but i felt like hearing your opinions and asking for help if anyone wants to :|
