Advice to lose 5-7 lbs in 3 weeks

So I have a feeling i’m getting proposed to in 3 weeks. I’ve been dating my boyfriend for 8 years and there’s been “signs” that i had a strong strong feeling it’s happening end of may. I’m 130 lbs and 5,3.I was 122lbs last summer but had to stop exercising due to heart problems that are still being investigated.I know an engagement party is planned after the proposal as well with a ton of family and friends.The reality is i’m not confident what so ever and i’m so nervous about not feeling confident with myself which will give me a ton of anxiety. I’d like to lose 5-7lbs in 3 weeks and i’m not sure how to go about it.I can’t exercise intensely but i do walk when i can, it just depends how im feeling.Does anyone have any tips?
