I feel like there no hope in Battling myself

Omg it’s so hot today. I just did 3 miles again and I swear I almost passed out. I had to find a hose as soon as I finished .🥵 3 miles use to be cake for me. Why have I let myself get so freakin outta control. I’m so frustrated. It’s going to take me forever to get my weight down. 😡 I don’t need a pick me up that’s not why I’m writing this, I’m just venting about how much I absolutely hate and am disgusted with myself, lol. I know how long this journey is going to take, I did it before. This time tho I’m starting older so it will take longer. I just can’t believe I’ve let myself go like this.
