burnout or need a timeout?

Trigger warning: I'm in a lot of pain and seething in anger. I'm looking for a vent and hopefully if someone can share their experience and I can feel less alone. That's all - this is not an attack on all ADHDers or even just one (like my spouse) but I am really done with what ADHD symptoms have done to my life in all its many shapes and forms. 

.... guys, I'm struggling. Big time. I'm so angry, resentful and all sorts of fired up emotions that I couldn't tell you what is what at the time. I look at my spouse and I'm angry and rightfully worried that I've crossed into contempt and resentment in levels that I dont' know even if I could begin to explain to him, he listens and works on it, could even HE come back from. I've done too much and pushed myself too far and and trying to claw my way back (by setting boundaries or something) but it just doesn't seem to be helping. I feel like I'm treading water and my spouse is throwing stones at me, but I have so much water in my mouth I can't tell him to stop.  I'm running a marathon and he's slamming me with steel chairs but it's in the face so I can't communicate that hitting me with a steel chair isn't helping my marathon running time that is important to me. 

I've rendered myself voiceless and I have no idea how to even start to talk, scream, cry, shout - anything to get my voice back. 

I don't think my spouse ever intended to cause this much hurt and harm, but my god, I really don't like him at all. I want him to go away - I don't care where, but just go. It feels like having some quiet from him and his s**t is the literal only thing that will help me - despite me having therapy booked for tomorrow. I'm exhasted from this, I've dropped so many plates (responsibilities) and things that had to be dropped, prayed that the plate was rubber and that I could pick it back up. But he picks up NOTHING. He does NOTHING. I'm tired of asking and I'm tired of hearing 'could you just do me this favour??', 'could you just do me this solid?..." EVERY DAY but when I ask - it's a No. Flat out. No. How the hell do we non-ADHDers (or over functioning for some of us) even being to use the word NO? I really mean this. I have NO IDEA how to use the word No because I don't believe my using the word NO is taken seriously. It hasn't before, why would now be any different? 

I'm relatively healthy and look after myself, but I've got this belly that I'd like to blame on late night snacking but if I'm perfectly honest, it's a stress belly. Becauwse of what I'm dealing with and how much I'm doing that is too much for me. My body is asking for me to stop, say No, rest, etc. But what about when you don't even want to be asked to help your spouse? Your spouses actions on the daily are an actual trigger in your heart EVERY DAY???? Your spouses words are a trigger every day??? What do I even DO with that information that I know? What can I do?!?!?! It rests on the fact that my emotions and well being are based off of someone else doing something - which I know in my brain doesn't work, but by god... my heart feels like if he would just: [insert action here] things would be better. 

I can't tell if I'm about to have a breakdown, I've already had one and this is the outcome, or if I need a timeout or what. Or if I need to send my spouse on a time out or break or something. I literally have no idea. I hate what ADHD has done to me - and I don't think I even have it. ANd I'm frustrated that my spouse is not doing his part in all this. That's the crux of it. I'm angry, hurt and resetful because I dont' believe my spouse is pulling his own weight in this relationship/marriage. It's been like this for 4 years. I've had enough. But I don't know what to do with this information except what I'd LIKE to do is blow up at him and tell him so many mean things that I know will absolutely crush him... because then I would feel better that he has an OUNCE of feeling the pain that he has caused me with his lack of.  But inside, I'm a good person and I know I couldn't do that to him because I wouuld regret that terribly. 

When he speaks, I think he sounds ridiculous. I don't know him anymore and I don't understand him. I don't understand where he comes from or what his reasoning is behind something. i don't trust him. I dont' feel safe with him emotionally. And to be fully honest, I'm not sure I want to work on any of those things. I just want him to go away for a while OR him to step up and start the conversation again about our marriage. I'm tired of this being on me, day in and day out. Every effing day. The responsibilities and weight of all it has just crushed my shoulders. 

I don't know even where to beging to address this. I don't know how to address this. I'm in therapy -0 an awesome therapist and I'm TIRED of spending my money talking about my spouse and his impact on me in my safe space. His unmanaged ADHD, anxiety and depression TAKES UP SO MUCH SPACE and it has upset me and angered me to my own health detriment - how to I even begin to take back space? 

Do I need a break from him? The relationship? I have no idea. We haven't even gone to couselling.
