Welcome to the forums
@@lex . Sorry that you have to wait so long for a definite diagnosis but it sounds as though you are getting treated as a T1 for now. A lot of T1s put some weight back on immediately after diagnosis as lack of insulin can cause weight loss, so you may find that that the insulin helps you with weight gain. There are other types of diabetes than T1 and T2 which they may or may not also need to rule out.
Are you in frequent contact with the diabetic team to adjust insulin doses? Do you have a way to test for ketones and have they talked to you about hypos?
The technology available for new insulin dependent T1s is amazing (eg insulin pumps and continuous glucose monitors) and there's very little that diabetes will prevent you from doing. There is a steep learning curve at the start, but you don't have to learn it all at once. (I'm still learning stuff after 50 years of it.
)
T1s need to balance their injected insulin to their food, exercise and metabolism because they don't make any (or enough, in the case of new T1s). T2s are insulin resistant and generally start out making too much insulin, Reducing carbs works well for them because they are literally carb intolerant, so a lot of the diabetics on here are on low carb diets. Bear that in mind when reading the forums and the T2 threads because although some T1s do low carb it is definitely a choice for T1s.
