Poor little man has not been in the best of moods today, like the picture says anytime I tried putting him down (or tried to leave the room to go to the toilet) he'd start crying. He's been amazing lately and it's not nice seeing him get so upset. Especially when I don't know why he's upset, and when Ive been feeling so low and down, I've been put back on antidepressants again and they're at that point where they've kicked in but because they're still new they're making my mood worse before it gets better. I'm just scared I'm gonna feel this low forever and just not be a good influence for my son.
