If it's making you sad, fatigued, and made you have troubles in sleep, then your post belongs right here!!
It's okay if you can't handle the heat

Where I live, the sun is punishing, and I can't even go to school without being completely drained, and I have missed classes because of that, and as I recall, my depression made it even worse, making me completely fatigued, not wanting to outside, kind of like what you're going through. However, you seem to have a good timing plan, you just need to follow it, and take your kids early to the beach so that all of you have enough time to enjoy.
I'm so glad that you're trying to break free of that feeling, and that is something not everybody can do!! You should be proud of yourself
I wish you all luck for tomorrow! I hope it goes well for you all!!
