I didn't know that about birds, its very concerning. I hate to imagine what preservatives are doing to our bodies. It can be hard to consistently eat healthy, home made meals with a busy lifestyle. Good to see you're making small steps.
Don't be too hard on yourself about not checking everything off your to do list, maybe even try and put a few less things on there if you can. As for the clothes, have you considered Marie Kondo-ing some? I'm sure you could minimise some and fill up a bag for good will.
