I am so sorry to hear about what you went/are going through. I cannot imagine. I can only try to help by telling you what I’ve experienced and give you general advice but I hope it helps even a little.
I only had a mild-moderate TBI from martial arts. But I have noticed when I’m talking I tend to forget words right in the middle of a sentence. I also suffer from migraines that can last weeks (right after the TBI I had a constant migraine for 3 months plus neurological slowing-it felt like I was drunk). As i healed, and this happened for a good year to two years afterwards, if I hit my head on something like the wall or anything really, it would trigger a migraine.
My TBI was in 2016 and I’d say by 2018 I was back to “normal” besides migraines. Before, I couldn’t sit down too hard or I’d jostle my head and re-concuss myself.
As for the emotions, I have bipolar, but the concussion made my emotions CRAZY. I was hyper sensitive to sound, light, so many things in my environment and if something set off a migraine, I would immediately get really pissy. That is not normal, not even for bipolar. At the time I wasn’t medicated correctly, so I was a little goofy anyways but the concussion really made me emotionally labile.
Bc of the bipolar, I have been on numerous anti-epileptics like depakote, topiramate, trileptal, etc. there are some interesting side effects to them. Some of that is weight changes, dizziness, sleepiness. But for the most part the side effects tend to wear off after the first couple of weeks. The weight changes can linger, though, unfortunately, depending.
As for explaining disabilities/difficulties from injuries to able-bodied people, that can be a real challenge sometimes because they’ve never experienced what you are going through. Hopefully, if they are empathetic, they can at least be kind and try to understand. Then you have the others who don’t try. I don’t waste my time with them.
There are a lot of a lack of accommodations in public and that is beyond not right. I’m sorry you have to deal with that. It helps to have a disabled parking placard/license plate, for me at least. I understand that is only one part of much more that you and others may need and I wish there was more I could do.
I have been very lucky to have support from family and friends. I’m so glad you have had support as well!!!
The important people stayed with me and I lost the people who didn’t deserve to be in my life anymore after my TBI.
I hope that answered some of your questions! Feel free to message me whenever!
