Rinoa, take a deep breath. Everything will be okay. Diabetes is not something that you need to freak out about. It is a shock to find out when you have it, let alone Type 1, however it is totally not a death sentence. First, it is advisable to visit a website at blood sugar 101. Jenny Ruhl (I think that's her name) is a diabetic and has created this website to help educate you on diabetes. It is an extremely helpful website. It really explains quite a bit. Also, most people on this forum follow a low carb/high fat diet. I do not know much about Type 1 as I am a Type 2, but there are many on this forum who are Type 1 and manage their diabetes quite well and are living very healthy lives. One individual (Richard) is very informative and has lived with Type 1 since the age of 6 and is now in his late 60's/early 70's? And, he is very healthy. Peruse the forums and look at the recipes that many have posted here. Most are very delicious and easy to make, and you will not feel deprived whatsoever.
As far as having to take shots; it's really not that bad. You really need to be able to give yourself your shot(s) each day because if your husband happens to be not available, it is important you can give yourself a shot. Trust me you will get very used to it. It is no worse than testing your blood sugar with meter than using a very thin needle to inject your insulin. I take 4 shots a day; 3 bolus of Humulog (fast acting at meals) and 1 shot at bedtime of Levemir (basal long acting). I can tell you, I do not like giving myself 4 shots a day, but I have to do it in order to keep my numbers down. I have been on both insulins for a little over a month now and I'm still having some highs and lows, but learning what causes my blood sugars to spike and what doesn't by testing with my meter.
I am sure many of the other people here will be introducing themselves soon to you. My advice to you is to pay alot of attention to them. All the people here are very supportive and understanding, and will help ease your anxiety about being diagnosed Type 1 Diabetic.
It would be helpful if you give us some information about you like what your numbers are, what types of meds you take (including any supplements), what caused your hospitalization and such. Everyone will certainly give you very researched advice and help whenever you need it.
