Sounds like some wise mind thinking would be a good thing......maybe you could take this information to your T & he could help you think through what changes you can make right now to lessen your stress......sounds like your brother living with you is about the last thing you need.......maybe your T can help you with some boundaries & maybe help you understand that they aren't attacking you about your son even though it's how your emotions are feeling. I know that postponing a class isn't anything I would have ever wanted to do......but maybe you can talk with your school & possibly take an incomplete in the class & go back I finish it next semester after maybe more things have calmed down or you have been able to find some help & maybe a better place for your brother?

Really sounds like what would help you best is a lot of problem solving techniques & someone to help you work through to help you see your options & how to set the options in motions for your well being.

If you have a breakdown (I've been there also)......you won't end up with any other option than not finishing the class.....so maybe it might be better to try & postpone finishing it under your own control.

I can definitely understand the stress you are feeling.....there is no one dealing with all of that that wouldn't be feeling that horrible out of control feeling that you are experiencing........maybe you could even have your T write a note for your school saying that it's for your mental health that you need to take an incomplete this semester.....that way also you don't have to take a grade either if it works like the incomplete I ended up having to take one semester.
