Social anxiety

Ok so....I kinda need some advice /opinions. ... my bf and I have been together for 8 years.. (well fiancé now).. :) ♡ .... and for whatever reason I get extremely anxious whenever we go outside and there are females around. I'm not insecure about myself I'm not insecure with him I mean he's asked me to marry him we have been together so long and have been through so much I mean he's with me and not going anywhere and the same is true for me. But how come I still get literally 10× more anxious when we go out even if it's to wallmart I'm like OMG there's so many people!!!! There are too many females here and they're looking at you and giving me dirty looks so I'm giving them right back or they're just staring to hard like... .. females .. please learn to keep your eyes to yourself especially when you see a guy and his lady right next to him... thank you for the flattery but stop now. Keep your eyes on your own man or to yourself dang!... And my bf either looks at me shows US off or focuses on what we are doing and pays no mind to any females ... but if he even looks in the direction of where any female that is looking is I get like pumped and I want to go jump on them both (ok a little extreme) I just get really more anxious and I let my fiance know how I feel at that moment whether it's with a look, or I start a new conversation or point out something random. . Or on a worse day I just tell him straight up ... um babe... there's a girl over there looking at you can you just look at me and not turn or look that way until she is gone or like idk we can show off in front of her or something. I mean I have anxiety anyway but it's definitely amped when we are out. I don't understand. I know he loves me and only wants me and only has eyes for me. He understands what I'm going through and is doing the best he can to help me through it. He doesn't look any other female doesn't flirt or even talk to them. Like if we have to cash out at the store and it's a girl he will let me do it and just love on me the whole Time and like show off his ring or something or just if I kinda give him a heads up that I'm getting "that feeling" at any time he will do something to try to comfort me but idk it's still an ongoing struggle for me. I feel bad because he likes to do outgoing stuff and so do I. like for example going to a water park he wants to go to one and so do I but I'm afraid and anxious about it because there's gonna be so many "naked" (short shorts tank tops swim suits etc..)people there . I don't like that. I told him I want to go but I might need some Ativan to get me through it. (Jokingly about the actual ativan.) But you know what I mean. Idk I get afraid to go outside sometimes because I'm afraid i will flip out and cause arguments that are completely unnecessary because I know where his mind and heart is and where mine are but I can't control that I feel like this and i hate it. I don't understand. Does or has anyone else felt this way? What do you think about this? What should i do? ... (apart from go see a doctor lol yes we have already had that conversation but I'm stubborn that's a last resort lol I don't want meds ... I'd rather have herbs.. not sure I could be treated with herbs due to my profession.. But still .... last resort).... anyway any thoughts or opinions or possible solutions? Do you think I'm dealing with it badly how I described above? Any suggestions or other ways to deal with this? Uggh I hate anxiety. I hate this feeling. P.s. this is really the only BIG issue we have in our relationship and has been ongoing. I want to find a way to either stop it or make productive and visible steps to stop it or something before we get married. HELP!!!!!
