I pretty much hated going anywhere with people alone, but recently, I've been forcing myself to get out, so now I feel like I have managed to become more or less comfortable being in public, and no longer feel like every single person within viewing distance is staring at me and judging me/laughing at me.
Also, I wouldn't go to any of these in the first place, but things like parties, bars and clubs would be quite awkward for me to go to alone, or really, in a group as well because those kinds of places are not where I want to be, unless by party, you mean video game party/LAN party/birthday party with your friends in the basement eating junk food and playing Smash Bros. or something of that sort.
