Yes, Wil, it will eventually be OK. I know it doesn't look that way right now. I am glad that your margins were good.
Right now, you need to focus on getting yourself physically well, and you need to grieve the loss of the way things were. You may need help with both. If your surgery was only 5 weeks ago, it isn't surprising that you still have pain. You have been through major surgery. The pain will gradually lessen, but for now, listen to your body as well as your medical professionals with regard to what you can and cannot do. You might want to consider getting a hernia belt so you don't add a hernia to the mix.
I would strongly suggest that you find an ostomy support group in your area. This site is good for asking questions and getting answers, but if you can join a group, you will find that really helpful too. You might want to consider professional counselling to help you grieve the loss of the way things used to be. When I was diagnosed with cancer, and told that I would need an ostomy, I sunk into a depression. Professional counselling allowed me to climb out of that pit. You are facing extraordinary circumstances - most people have no idea what an emotional upheaval this is. There is NO shame in getting whatever help you need to cope with this.
Wil, arm yourself with information. It will feel overwhelming at times, but you need all the information you can get. This site is great for that. There always seems to be someone who has faced whatever challenge you are asking about. You will find that ostomies don't come with a user manual, and your health professionals will invariably answer a lot of your questions by telling you that everyone is different. That phrase will make you crazy, but the reality is that it's true. You will find on this site that people have a wide variety of experiences and solutions, but you will need to find what works for you. We can help by telling you what works for us, but bear in mind that just because something works for me, doesn't mean it will work for you.
Have a look at past forum topics, and the tips from members. That may help answer some of the practical questions you may have. I suspect that what you want to know, more than anything, is will it get better. Yes, Wil, it does. I am living proof that it does. I am so glad you found us, Wil. Keep asking questions - we are always here for you.
