Going on vacation with my boyfriend for the first time, and...

So I have never traveled or gone onto a plane so my boyfriend surprised me with plane tickets to go to Florida to go to Disney and Universal for the first time ever. I'm turning 20 next month, and my boyfriend is 25. We've been dating for 8 months, and he's been my first for everything.

I work in a small store and we were all talking about everyone vacations coming up, so one of the older ladies was asking me about if I got like new clothes and this and that. To get to the point we started talking about bathing suits. Now last I weighed myself I was 193 pounds but my boyfriend has been the best with telling me I look amazing, and recently I signed up at the gym and I go with him just about every morning. I feel like I lost a lot of weight because I have also changed my diet, so I proudly showed off my new bathing suit to my co worker.

I love the way two pieces look so I try to get high waisted bathing suits. I was also super bloated in this picture cause I'm getting my period lol, but I thought I looked really nice in this. My coworker turned around and she said "oh sweetheart that is way to small you need to shop around more." And it made me feel so self conscious about myself because I felt awkward even thinking about wearing my bathing suit around my boyfriend.. not only that buuut my best friend helped me pick out lingerie that I can surprise my boyfriend with when we go away.

I am super insecure of my body, and my boyfriend knows this and he always tell me that I look amazing when we go out, but now after my coworkers comment I am super nervous to wear the lingerie for him

This is the lingerie set that I got him, and I mean I was very insecure buying it so I am nervous to wear it in front of him.. am I going crazy because I felt fine before my coworker made her comment. And I've been feeling better about my body since I've been going to the gym with my boyfriend, but I'm just nervous to wear it.
