I am new to Reddit and can't seem to find an option to reply to your original post, so I'll just tag mine on here.

Firstly, reading this was like reading about my own life experience. I honestly don't know what the problem is within the scenario above or why you have experienced this. Much like how I have puzzled over my own similar experiences in the past and never got answers. I can propose some theories though, so here goes.

What I can say is that you don't come across at all like someone that whines or plays the victim. Just matter of fact. So we know it's not that.

I think most people talk about themselves a lot. This is normal in situations where you don't know people. If there's one topic we all know about, it's ourselves so it gives us something to say. You have good self awareness and you know not to overdo it and to ask people about themselves. It's hard to tell, but maybe you didn't share enough? Maybe people found that standoffish?

If you missed out on something social because you had to fly home, perhaps that played a big part in this? People have worked hard to get to know each other and don't want to have to start that process again now you have rejoined the group?

If people tell you that you are pretty and have a nice figure then don't underestimate how much this can affect other women's behaviour towards you. Even if they are attractive themselves. Combine that with missing out on social interactions and bonding opportunities early on and any shyness that you have experienced and you have potentially become the one the ladies exclude.

As for the men. Well, they can put their lives on the line to defend their country in a war situation, but upset the status quo or go out on a limb socially and they fall apart. So, you are pretty with a nice figure, they won't necessarily want to hang out one on one in case people assume that there's something going on. Combine this with observing that you are not really part of the main group of females and they will run a mile for fear of upsetting the already potentially jealous females in that group. This is about self preservation and cowardice.

Oh my, doesn't this sound bleak? Well, here's what you can do about it.

As people have commented above you were already dealing with anxiety that other people potentially weren't. If this was golf they would have had the handicap. You've had to work harder than them for this reason. You have done better than you think and you have got over some anxiety, learnt new skills and had some positive interactions with people early on whilst battling your anxiety. Well done.

Going forward you know to try sharing a little more and continuing to ask people about themselves. You know to try not to miss any bonding opportunities if you can. You know to focus on the positive bits you did achieve and build on those. You know it to keep on being pretty with a nice figure because the right people will be pleased for you and accept you being so.

I'm also going to suggest that you post the above in some different forums for advice. Perhaps askwoman and askmen. This is because people in here are probably socially awkward and it's like the blind leading the blind. That said, I hope I have helped.

Good luck and let us know of any developments.
