I’m sorry it is such a struggle for you at the moment - managing diabetes on it’s own can be stressful enough when its not going to plan and the same can be said for pregnancy so the two combined are not easy. It’s hard to heap praise on yourself, particularly if you have depression, but if your DSN says your are doing well, take it you are! They’ll have seen enough women with Type 1 through pregnancy to know.
You are in control here Kelly, it’s just really tiring staying that way, but the fact you are so exhausted just shows how much effort you are putting in and you’re making sure you keep safe by being more cautious about going out alone when worried about hypos.
Do you have any kind of psychotherapy support at the moment? If not could you ask your DSN about the possibility of a referral? The physical strain can increase the emotional pressure and vice versa so extra support might be needed to help you through it.
You can call the DUK Helpline for support, even if you just need someone to listen to you cry for a bit, they’ll listen. (the number’s at the top of the page, but they’re only open office hours, 9-6). I’m glad you’ve reached out for support and plenty of people here will try their best to give it - keep in touch and keep at it, you may find that it starts to get easier as your pregnancy goes on, at least for a little while, but I cant tell you when that’ll happen, until it does and during and after and when you have your little bundle in your arms we’re here for you.
I realise I haven’t given you any of the practical advice that you might be after - I’ll leave that for someone with experience to share.
