I'm spiraling downward.
What do you mean by spiraling downward?
I'm chock full of anger at the moment.
If you are feeling extremely angry, you should talk to someone. I would advise talking to a therapist about the issues you are facing so they can help you.  Worrying by yourself about the anger you now feel could push you further down that spiral.
Don't talk to me like you know me. I'm not weak.
I'm not trying to imply that you are weak, I just mean that issues such as this are almost impossible for anyone to solve by themselves.  Luckily, therapists know how to listen to what is troubling us, and to offer guidance on how we can fix the problems we face.
