Hello,
Firstly, many congratulations on your wonderful news
Well done also for getting off the cannabis and alcohol, that takes a lot of strength and isn't as easy as it sometimes may sound.
I think it's lovely that you're rebuilding your relationship with your mum, I hope that's going well.
If you ever need to talk, I'm here. I have three children, (hubby and I have five kids between us) two of which are very young at 13 months and just over 2 months. I really struggled in pregnancy because I have mental health problems and it seemed to trigger massive anxiety. I don't know about where you are, but over here in the UK there is something called the perinatal service which your midwife refers you to if you're pregnant or a new mum and are struggling with mh too. Perhaps there's something like that where you are? Anyway, if you do want someone to talk to then feel free to PM me, I know exactly how hard pregnancy and mh can be!
I do hope you can enjoy your pregnancy, it's wonderful feeling them move for the first time
