When you first get diagnosed / realise you have an SCI then it is a lot like grief, you are sad and angry that life is now different. That you may have lost the ability to walk / move and even talk. You are now disabled and that takes getting used too. If you can walk, you are likely to feel guilty that you walk and others cannot. If you cannot walk you have a steep learning curve, how to get around in a wheelchair, how surfaces make such a difference and how some inclines that you used to walk up without even thinking about it are now not currently possible for you or are ridiculously difficult.
Regardless of where your injury is the one thing that is almost universal is you are likely to have to have a bowel management system and bladder management system.
For me this was the biggest challenge in coming to terms with my SCI. Your routine will likely take an hour or so every day either in the morning or for some people in the evening.
