How do I get back to where I was I feel like lost everything I worked so hard for?

Hello to start off with I love my family and wouldn't trade them for the world. I just don't know what else to do I feel like im gonna go crazy. Summer 2009 I came home from school in pittsburgh my gf at the time had been there for me and waiting for me to finish school. I had overcome so much adversity and criticism no one believed I was going to graduate or be successful because before I went to school I chose the wrong road working part-time jobs to cover up my association with a million dollar drug cartel. Almost losing my life is what forced the drastic change and my love for this woman I didn't want to lose. So finished school back home doing an unpaid internship living with my dad wasn't what I expected but I had a plan for us to get married buy a house and live happily ever after. I ended up getting the job where I Interned I used my first 3 checks to purchase the Engagement ring. Now my gf at the moment has two children by two different men but was just the sweetest woman I ever met. I wanted to do right by her and get married first before we moved in together. Me not having any children of my own wanted to be married when I did have a child. So I proposed it was special were in love set a date for two months. Before we got married I sat down and typed up a savings plan on how we would within a year buy the house of our dreams and car. We got married our goal was in sight but not complete so we rented a condo from a friend I worked with. Newly weds all on our own it felt perfect. Until I noticed my wife had an anger problem and was not the cleanest person in the world. The anger problems took a turn for the worse when it turned into disrespect. Laughing when im trying to explain things, turning her back on me, getting up when I was talking and leaving the room. The arguments were about the craziest things, things people don't argue about. Now Im not saying Im perfect there are two sides to every story. If you ask my wife she would tell you the same thing. Three months into our marriage we got pregnant, a blessing, and a curse, she got 5 times worse. I said she's pregnant so I wont make any waves I just wanted to be happy. Now im dealing with verbal abuse this isn't me I donut deal with stuff like this I kept saying to myself. Still didn't want to make any waves this is what I always wanted so married and my son on the way so I just dealt with it everyday for 7 months and buried it inside I even stopped arguing back. We only had one car because of our savings plan so my day to day routine went like this. She isn't a morning person so I would wake up 6:30 wake up the kids 5 and 3 get them washed dressed make breakfast wash and dress myself while they ate. Have her clothes ready and left the house at 7:15-7:30 because she didn't like waking up early I would have to drop her first then drive back across town to drop the kids at daycare and that was just the beginning. Then because we only have 1 car and I worked out of state I had to double back to her job and park the car from there I had to catch a bus to get to the train station and catch the train a 40min ride once I got off the train I had to literally run out of the train station to catch another bus just to get to work 5-10 mins early. So If I ran into traffic dropping off the kids or missed the bus at her job or missed the train or missed the second bus all of which happened I was late for work or had to pay steep taxi fares in order to make it on-time. Still dealing with everything else was taking a toll on me and effecting my work performance. So in order to keep my job I had to buried even deeper. After living in the condo for 5 months we bought our house brand new found the house we wanted they were building a new development we found it halfway threw the 4th home so we were still able to have a lot of input on the layout. We closed in a month it was so exciting to have a home of our own brand new, still dealing with the anger issues. Still my day to day routine. Maternity leave got alittle better because she didn't have to go to work so I drove to work. Camryn our son was born my pride and joy. So we decided to set another goal what if I go back to Radiology school two years and I will be making almost double what Im making now and you wont have to work we both saw it to be a great Idea. Im 26 she's 23 we are still young. So before having to go back to work she told me what if I work and you go to school she didn't want to put the baby in daycare and i could do my classes online. I insisted no its not in our plan she pushed and pushed and argued and fussed until I gave up and said ok. Worse mistake of my life now I have been unemployed for 6 months we struggle to pay our bills and she hates her job. Now I here that she doesn't want to work and I should find a job and I have been looking for 3 months idk what to do. The only positive is that I have 1 year left of school that's if w
