TW depression

This is so embarrassing to even post so please no judgement, but I've been having a hard time with my depression lately I'm a single mom living alone and sometimes I'm so overwhelmed I forget to take care of myself. I haven't showered in about a week & have gotten a severe tangle in my hair.. it's the size of a golf ball and I've spent the last hour using detangler and conditioner, coconut oil ect with no luck.😭😭 What can I use to help I don't want to cut my hair it's right on top so it would be noticable I have to get this out thank you for any suggestions
