just need support and understanding

Hello. This is my first time posting. My husband of almost 5 years has (not yet formally diagnosed) adhd. He has just started seeing a psychologist for testing and hopefully medication. I am really struggling knowing potential relief for myself of his behaviors is hopefully around the corner, however I also understand it will not be immediate, and not without lots of work on both of our parts. I guess I need guidance and support related to the fact that I am at the end of my rope and hardly want to be in the same room with him anymore. His nervous energy, pacing, tics, etc. Are driving me insane. He just gives me an uncomfortable feeling and creates anxiety in me. Is this normal to be so "over it" that you just don't even want to be in the room with them? He is getting help (after years of me nagging) and I'm grateful for that and proud of him, but it is still so tough. Maybe its more difficult because we are on the ISP of him (hopefully) getting better. You know, how the last mile in a Marathon is the toughest because you know you're almost there. Also probably important to mention that we have a 3 year old. I really wantto stay a family and do what ittakes, but I am so tired and so frustrated. I've tolerated it for so long. I think I just feel done. Like come back when you're well. Otherwise get away from me with your craziness. My husband mostly has nervous energy, some very mild tics(like neck popping and shoulder shrugs). He taps stuff, taps his feet, pcks his fingernails, and paces. He also gets irritable and can't tolerate stress well. He does not have problems at work. He is not spending like crazy or cheating or anything awful, but the daily energy he exudes is just awful. So, sorry for being long-winded, but any advice on how to be more compassionate, tolerant, etc, so that I can make it through the next few months? If you have any other questions about the situation I am happy to answer them as well.
