First off, please relax a little bit and find a little bit of enjoyment in your life. You can do very well without CHM or pump although both of those tools are really great. I lived with T1 and had a full, active life for 48 1/2 years before I got my first pump and I still don’t have CGM.
Many people say that one of the best guide books is “Think Like a Pancreas”. For meals, do two things; 1) choose foods that you enjoy eating, and 2) make healthy food choices. You may have some conflict with those two guides, so let “Healthy” prevail. You need not eat only special diabetic foods and I try to avoid anything labeled like that.
I’ll presume that you manage your diabetes with MDI (Multiple Daily Injections) of a fast acting insulin plus a background or long lasting insulin. If so, I suggest that you learn and get in the habit of counting carbohydrates in everything that you eat - food packaging lists the carbs per serving. At first that will feel overbearing but after a while it becomes old hat. If you want help figuring how to get the right amount of insulin into you for meals, just ask and I’ll share with you some of my methods.
Just be careful in calculations while you are learning - and don’t get discouraged if you make a mistake and two hours later you have a weird BG reading - I make mistakes counting carbs especially when eating in restaurants - just think back to where you may have slipped up and learn from that. I’ve been at this for 60 years and I’m still learning.
