Hi Jenniewoo, welcome to the forum 🙂 Sorry to hear about your diagnosis - how did you come to be diagnosed? Have you been put on any medication for it? It's unusual, but not uncommon, for slim people your age to be diagnosed with Type 2 - have you had symptoms for long? We have noticed here, particularly in recent months, that some people are being misdiagnosed based purely on their age, because some GPs think that Type 1 diabetes is something that only happens to children. However, it is more than possible to be diagnosed Type 1 at any age - I was 49.
If you are at all unsure of your diagnosis I would ask to be referred to a diabetes specialist so that they can do some tests to establish whether your diagnosis is correct.
Please ask any questions you may have - there are lots of friendly, knowledgeable people here who will do their best to help and support you 🙂
