Body Image issues meets Boyfriend

Lou

So....my boyfriend just asked me if I wanted to go with him and his sister&her boyfriend to a nearby lake tomorrow for a lake day, but I’m SUPER self-conscious (at least in public, in front of my best friends/family I don’t care), I never wear anything that shows my stomach, legs, breasts, or my shoulders outside my house...the most covering swimsuit I have is semi-low cut, and shows quite a bit of my legs and is semi-formfitting....so I’m freaking out! My boyfriend has only seen me wear something knee-length during a formal dance where it was a short dress thing. Other than that I’m always wearing jeans (without holes), a t-shirt, and when the weather permits, a sweatshirt/hoodie. I’m really not comfortable showing my body, and I’m almost at the point of a full-blown anxiety attack. I want to go, I really do, but I also have anxiety to along with my self-image issues so I have to worry about the constant nagging in the back of my mind saying that everyone is staring at me and judging me negatively....I don’t know where I’m going with this, I guess I just needed to vent about it....I’m really tempted to just wear a older t-shirt and shorts over my swimsuit, but also I hate the feel of wearing wet clothing...I don’t know what to do at this point. Sorry for the long post but thanks for reading and letting me lay it all out.

UPDATE - Everything went okay and we all had a lot of fun! After going to the lake we went back to his house and were sitting on the couch talking with his sister&her boyfriend and I was kinda cold but me being my anxious self said nothing but him being the amazing boyfriend he is noticed and asked if I was cold, I can’t lie to him so I said yes, but its not a big deal (just trying to downplay it) and he immediately got up told me to wait then walked to his room and came back with one of his sweatshirts and gave it to me (he has never given me one before) so yeah, the day/night was absolutely perfect 😂🥰😂
