This is such a weird place sometimes.
A 25 year old man got raging drunk ( by the description of what he's saying he drank and the fact he couldn't find his way home) and decided to attempt to drive home and gets loads of sympathy for his "woe is me, make me feel better GAF" post.
So yeah, has a high quality education at what he calls a high end school, but its incapable of using a smartphone to call a cab, asking a barman to call a cab or along anyone of the other adults in the bar if they had a can number?
You really deserve everything that comes dude, and is time to stop making thin excuses for shitty life choices and start acting like an adult.
The guy is *unable* to do simple life skills like calling himself a cab , he also clearly has issues functioning in society and has ( or at least has a history of) mental health issues yet people are telling him to just up sticks and move to another country....
"Stop with the anxiety and mental issues, just start being an adult, sheesh!"
Wow, guys. Some of these comments are beyond terrible. The guy obviously already knows he fucked up, he spend many, many sentences telling you how lowly he thinks of himself because of this incident. The problem obviously isn't that he doesn't get it. Why is there any need to keep telling him what an asshole he is for what he did, when he already thinks worse of himself than any of you combined? What does that accomplish, except of you making yourself feel superior?
OP: You are not trash, you made a mistake. We all make mistakes, the only difference is how we deal with them. You seemed to be on a great path, making friends, going out, having fun.
Realize that your collegue INVITED YOU to hang out with you. Not only that, but it seems like it wasn't a one time offering but he regularly wanted to spent time with you, even though he could have just hung out with his girlfriend. He likes you and wants to spend time with you. Seems to me like you are friends. That also means that you can tell him if you don't want to do something. That's part of friendship. Don't be afraid to come off as weak - we are all weak in our own ways - and not wanting to get dead drunk certainly isnt a weakness
Leaving you alone in a bar is an asshole thing to do, but only if she would've just left you there without asking. But she told you - why don't you ask to tag along next time? Why don't you tell her you rather don't want to stay alone at a bar? Nobody likes to be suddenly abandonded on a night out with a friend. She'd probably understand why that would feel awkward for you. Most people feel the same way and are afraid of the same things about social situations like that. Be aware of that and don't be afraid to open up to people who obviously like you.
Wish you the best.
