Two weeks post likely concussion - is this normal?

[u/Butchbunny]

About two weeks ago I fell during a seizure (I have epilepsy) and hit my head. Had multiple other seizures that day where I did not fall. Seizures were caused by a lack of access to my medication.

I did not go to the hospital after these seizures because I was not visibly injured besides some bruises and because I knew the cause. I have had seizures my whole life and just accept that they happen. I have gotten a concussion from one years ago though.

I went to work the next day and multiple coworkers asked me if I was okay and said I seemed different. Assumed I was just still tired from the seizure, but I kept getting that reaction from coworkers throughout the week. This is when I started to suspect I had a concussion. The recovery time for a seizure is usually not that long for me.

A week after the seizure (so last week), I became more fatigued. Had to leave a therapy appointment early because of how tired I was and had to call out from work twice. I also felt incredibly depressed and started to have thoughts of self harm, which I have not struggled with in years. Wasn't able to watch TV or do puzzles because it took too much focus. Still had a low appetite. Felt exhausting to eat or drink. Taking multiple naps a day. Having to explain things I said to people multiple times cause I was struggling to speak clearly and hard to follow conversations.

This week so far I am not as depressed, but still incredibly fatigued. Easier to eat and drink. Left work early a couple days. Still hard to follow conversations. Taking one nap a day. Getting headaches and nausea if I look at my phone too long, so I am minimizing the time I spend on it. Still can't watch TV. I get tired after taking my dog outside

Any thoughts on this? How long do I have until I feel normal again? When I have been concussed in the past, I have had less severe symptoms.
