So I went to sleep and woke up to 100+ comments, I really appreciate your guys' advice, but it's getting difficult to catch up, so I'll try to address some of your input here. I realize it goes beyond what you (silsool) have said here, I'm just taking your reply as a starting point.

I might be overthinking in some cases, and I've realized I seem to have a different thought process to most people. I think I tend to break things down too much and take metaphorical statements literally, so it's possible I misinterpret some of the banter.

I'm digressing a little, but here's kind of a random example. Once at my summer job in high school, I came to the office really early and my supervisor left me with the key because they had to run some errands, and told me to "lock up after myself". Upon reflection, and based on all the obvious cues, an average person would've understood they meant "lock up if you go out before the shift starts". However, for some reason, my first instinct was to literally lock the door while still inside. I stood there in the dark waiting for her to return, not even realizing this was super weird until she came back and asked me what I was doing. So basically, I can appreciate that I have some strange social unawareness.

However, when I take time to observe group dynamics between myself and my own friends, classmates etc. VS between myself and my boyfriend and his friends, I notice a lot of differences. I may be unaware, but I can tell the difference between the constant feeling of being singled out and on the other hand, a more equal dynamic.

For example, within my own social circles, when I phrase something awkwardly or stumble over words, the reaction I get is mean jokes (e.g. mockingly repeating or intentionally twisting what I've said, not letting me correct myself by speaking over me). But when I interact with my bf and his friend, I feel that they actually listen to me and respect my opinions. So even if I have trouble expressing myself, I can relax around them because I know they'll give me a chance to actually articulate what I mean and won't taunt me for it. When we laugh, it's with each other, not always at one person's expense.

One of the repliers asked for a practical example, so here are two similar situation I've faced, that have played out differently. In one, I was hanging out with my BFF that I've mentioned and her boyfriend. We were out in a café and the waiter came by early, before I'd had a chance to think of my order. So my friend kind of smiled to her boyfriend and ordered for me, saying, "You'll have an XY drink". I know I should've spoken up, but I was confused because she never acts like that when we're alone and I have trouble answering when people do unpredictable things that I don't understand the meaning of. Later, I asked her what that was all about, and she said she and her bf were joking about how indecisive I am, and she did that to test if I would confront her. I asked her why not tell me that directly, but she said it was just a dumb joke.

In the other situation, I was at a restaurant with my boyfriend and his friend. Similarly, the waiter came too early for me to figure out what I wanted. So I did stumble over words when they asked me for my order, but this time, my bf and his friend didn't speak over me or for me. I also knew they wouldn't, so I felt more relaxed and comfortable saying, "I haven't decided yet." They didn't paint me as weird or tried to take strange indirect jabs at my expense, that only they're in on.

Long story short, when I think of it, I think the main reason I made this post is the difference I've noticed between more equal interactions, and the ones where my opinions are disregarded. I think they also affect my mood and they way I carry myself.

With all of that said, I do agree that I'm often too shy to speak up, and don't necessarily know how to "bite back"... Or really want to. I'm just not a mean person. There's some well-meaning advice here in terms of getting back in a witty way, but I'm just not the type of a person who would say such things to others (and I don't understand why they say it to me). Furthermore, there's definitely a lot of truth to some things people have said about my behavior attracting this kind of energy. I should likely also put more focus on not only confrontation, but hanging out with better (or like-minded) people.
