Life feels so overwhelming

My brain is so overwhelmed with life. I feel like I don't even know who I am anymore. I finally finish Summer school and yet I don't feel a sense of relaxation or relief. My wife and I (my wife especially) is dealing with so much stress and it's feeding off of each other we don't know how to break lose. She has been taking care of her dad a lot since he suffered from a massive stroke in January (2013) and since school has gotten over I've been trying to go over there more with her to keep her company so she doesn't have to deal with her step-monster (step-mom) as much. Then we have to look for jobs for my wife's mom because she recently got unemployment and its our job to look for her and turn them in (also because she doesn't know how to navigate a computer that well).
My wife is dealing with a change is bosses at her work and she got a new schedule is isn't very fond of, so now it's at a point where nobody at her work likes actually going to work (she works with adults who have developmental disabilities). I give her props because I couldn't do that job. And she's always got doctor's appointments and friends/family wanting to do things for them here and there and it's like we never have time for ourselves or each other at them. We are both going crazy, and due to all of this stress we have been arguing with each other more and we never used to argue, we are not that type of couple. I'm so scared, frustrated, and angry. I cant relief her stress and I cant get rid of my own or my own stressors.
I've been having troubles with my counselor, so I'm having to seek help elsewhere for counseling. So this coming Monday I have to close out my case for counseling and find a new counselor which is frustrating as well. I haven't really seen anyone constant for about a month and a half.
I recently found a lump in my breast which freaked me out but luckily it's just a cyst so that is a huge relief. We can all breathe now.
We just don't know where our break in life is. I still haven't found a job, so I'm stressing out over finances. I know that everything will be taken care of but I don't feel like it's fair that my wife has to always take care of everything.
We would love life to settle down, for me to finally get a decent job, for mom to get her own internet and for our step-monster to hire people to help take care of my father in law. Then we can move on to the next chapter...
