In desperate need of a confidence boost!😩

I just needed somewhere to vent! I feel so miserable lately, and just really struggling with a lot of depression and part of it is my body!! I just don’t feel cute, or pretty, or sexy at all lately and it doesn’t matter what I do, or wear, or how many times my fiancé tells me how sexy and beautiful I am. I’ve been really pushing myself to eat healthier, and get a solid work out in every day just to focus on my health, and prepare for ttc soon and also to hopefully build up some confidence and help me feel good but it’s still not working and I’m frustrated and sad... today I was all geared up to surprise my fiancé when he gets home from work, and jump his bones but after (trying) to take some nudes I just feel really gross, and fat and just not sexy at all and now my good mood and excited ness to see my man has all gone out the window and I’m back to being as frustrated and sad as ever. It feels like no matter what I do my body stays the same, and punishes me. I’ve constantly got a stomach ache of some kind or a head ache and I can’t figure out what intolerances I have...and it seems like no matter what I eat or how much I workout I still CANNOT lose weight! I know this is the same old song and dance for many of us but DAMN I’m over it. I just want to be healthy, and happy, and feel good about my body, but no matter how I try I just can’t get there. I’m so so discouraged.
