Is there anything I can do for you dear? Is there anyone I could call? No, and thank you, please madam, I ain't lost, just wandering

Came home today after what can be described as a SHITTY day. Gosh! I'm sick of having terrible days! It's like I'm not good at ANYTHING! I'm sick of it! I'm so tired of trying, of making a huge effort to be good at something and fail every single time!
