Giving My Notice

I have taken a very, very long time to come to this conclusion. I have a lot of health problems that have gotten worse over the last year. I am absolutely exhausted from working fulltime(45 hours) with two kids, 2yo and 5mos. my body can’t handle this. Im also full-time in school.

I have decided to get an easier, part time job and apply for disability. (I meet the requirements)

I feel SO guilty. if anyone has any advice on how to give my notice, I would love that. I’m thinking to give them 3 weeks or a month. I will be explaining to them that this is in the best interest for both parties, as i cannot meet their (really high) expectations and provide the care i wish i could to the kids.

please help. i have a written notice already but should i send it through a text? we communicate primarily through that. would an email be too formal? I plan to do it this friday. i am also a live-in. So i will be packing as much as i can so its easier to get it all out in one go.
