Hi
@Tezzat1 and welcome to the forums. Not sure you'll get many replies at this time of the UK night but the international members like me are wide awake.
T1 can be a very hard diagnosis initially, just because there is so much to keep track of, but you don't have to get on top of it all at once, and it should get easier as you get used to it.
The bad news: insulin pens, carb counting. blood tests, potential hypos, carrying around diabetic paraphernalia...
The good news: though it's initially a shock. there are very very few things that diabetes stops you doing (yes, I think astronaut is probably out, but olympic athlete is in). In the short term, I'd hope that you are getting lots of advice from your doctors or clinic, but in the long term you should be able to take more control and make your own decisions as you learn how your own body reacts to carbs, insulin and exercise.
I might get a low which happens after going for a walk sometimes
(Yes, I often get hypos when I walk my dog
. ) As far as hypos are concerned, it's great that you've had one and can recognise the symptoms. I strongly urge you to always take fast acting sugar with you when on walks (or anything else) as if you have a hypo you need sugar immediately so it doesn't get worse. Do you live alone or do you have family or housemates that you can tell about hypos?
Insulin pens are a bit of a nuisance but they are way better than syringes (yes I'm that old) and should be easy enough for you to carry round so that you don't need to go home to inject (at least long term, I appreciate you may not yet be ready to carb count meals or inject while you are out).
I feel because I go bed bg at 4-5 I must eat more I wake up at between 4-5
If that's a 4-5 bg level on waking then that's pretty good, as it's the same level as your bedtime. If you're waking at 4-5am anxious about your levels then that isn't so good (no one likes anxiety or a broken night's sleep). I'd suggest you ask your team whether it's a good idea to go to bed a bit higher or maybe have a bedtime snack.
Anyway, it will get easier, and once again, welcome.
