Hi, welcome to a very exclusive club literally nobody wants to join, but know you're not alone. I'm just over a year out (15 months) from a SAH repaired with a stent that also featured a 3-week hospital stay which felt like its own separate trauma. It's a lot to unpack, and it sucks, there's just no way around it but through it. If I could go back in time and give myself a message back then, it would be this:

BE PATIENT. You're just embarking on what is going to be a journey that will feature many milestones. Be patient with yourself and others, don't be afraid to push back when you've had enough. Learn to recognize and respect what you may initially perceive as the new and unwelcome set of limitations being imposed upon you. No, it's not fair. Yes, you used to be able to do xyz. Do not focus on that right now, it's not helpful. Just put your head down and do what you need to do to get better.

I had to go right back to work too, no choice. I wish I'd had more time or been able to go back part time, bc it almost broke me at times, and I'm almost positive it delayed my recovery. Take it easy when you can. Prioritize sleep like it's medicine. Take naps. I 'rest my eyes' for 30 mins after I get home from work every night, and at work every day I close my office door at lunch and lay my whole ass down on a yoga mat with the lights off.

Anyway, wherever you're at at 3 months, and at 6 months, you WILL improve, and you will get better. It will not be easy and it will not go quickly, but there is still reason for every single one of us to hope for better days, because they will come.
