Life is stressful as a newly self diagnosed husband with NT wife!

All of my life I have struggled with fitting in, making and keeping friends and expressing myself. Learning to cope and becoming someone else(in mind) is coming back to bite me! Life is getting harder by the day and I’m trying to keep my head up and not stumble. Well it’s harder than it looks! I’m 29, own a house, I have a good paying job(that I hate), I have a 13 month old son, 9 3/4 year old yorkie poo, and my wife. Juggling home life, work life, and my mental health is an exhausting task. I’ve lived my entire life thinking I was a cold hearted person that had no emotion or feelings of anything. I didn’t have friends, even though I tried really hard, maybe I tried to hard. I had to learn to socialize by imitating people. I got involved with people that I actually thought liked me, well they just used me as a scapegoat. I got caught and arrested multiple times for theft or vandalism because everyone either told on me or made me hold the merchandise unknowingly. And yet I didn’t learn because they were the only people I could hang out with. At 17 I got a job at a movie theater where I met my wife now. When I finally turned 18 I had dropped out of high school, got my GED, got a job in a factory, smoked weed on a daily basis to feel normal. I could never understand why I struggled so much; being told I was depressed or I had a mood disorder, or anxiety, or bipolar....well why did the dozens of meds I had tried not worked then? I continued to think I was going crazy! By the time my wife(gf at the time) got serious, I had already learned to socialize decently well. Plus smoking(not cigs) took the edge off and made it way easier. I made my wife(gf) believe I was a normal person, just like I had done for a bunch of other friends. I began to make her my special interest, I became obsessed. We grew together, learned to live together, learned to co exist. It was great for the most part. We got married 4 years ago, bought a house 9 months later, then came the new car. Life was so good. I had my special interests(video games, computers, and my wife). I had my days or weeks of feeling empty and depressed, but I was able to cope. After that my wife got pregnant in December 2015. I wanted it more than anything. I was so happy. Well after my son came in September 2016, I was badly injured when he was 3 weeks old. 37 stitches into the left side of my torso, right at my ribs. Since then life has been a struggle. I had a huge breakdown in April, I had to go to therapy. I got diagnosed with ADHD, and was put on 90 mg of adderall a day. That increased my productivity at work and home, but my social skills and sensory issues had deteriorated from not doing it much, from the date of my injury to that day(june 2017). Now I don’t know what I feel, how I feel, or even how to express my feelings. I’m back to being weird about touch and I really have no friends to talk to about it. The friends I do have aren’t very good. And my wife is not being as supportive or understanding as I thought she would be. She just continues to say I can get over because I used to not be like this. She says that I CAN retrain my brain, or something like that. I keep telling her that I don’t know how and I don’t know why I don’t know how. I do so much to make her life easier. I do the dishes every day, take out the trash, do our laundry, give our son a bath most days, run to the store if we need stuff, Take care of the vehicles(3), make sure the dog is fed, cut the lawn....I no longer get alone time unless I sacrifice my sleeping time like I am right now, I no longer play video games(a lifelong interest) or play around with my pc(another lifelong interest) because I have no time and if I do it when everyone is awake, I’m constantly being yelled at or something for being on them. So I literally have nothing to be excited about after work. Because I don’t do anything fun for myself or anything, and bend over backwards for my family. But of course no one understands how stressful it is. I’m just so confused. I thought I was perfectly happy, and now I’m realizing It’s hard to be happy when you have a family that you need to care for and a wife that you haven’t been intimate with in a long time, no fun relaxing things to do(interests) and all you can think about is why do I feel this way? What did I do wrong? Why does no one believe me? Why am I stressed out so much?
