Ahh OP I am mum to a 6 month old baby boy and felt exactly like this - also had some help from the perinatal team and went on meds for a few months.
I hope your time with the team is helping, keep talking to them - although I know how slow a process it is and how frustrating having to do the whole thing over video calls is.
Meds aren’t for everyone but I found they helped me through the early months and I’ve been able to come off them now.
Do get someone to look at your tear again - keep calling your doctor or insist on an in-person appointment at one of those walk in clinics.
As for babies being boring and COVID times being rubbish, I think it’s a bit of both. Given that all we can control is what we do day to day, I’ve been trying to make the most of our time inside and give our days some structure. I’ve found it has got better as my boy has started to show a little personality and respond a bit more/slowly learn new things too.
Each weekend I make a plan for the upcoming week - just 2 or 3 things to do each day (for example a live online baby class - there are lots of free ones and I’ve found it helpful just to be reminded that there are still other people in the world!, specific time to read books or sign nursery rhymes, making something (like a cake), getting a wash done, sorting through or clearing something etc. It sounds silly but even if you don’t manage it all, it helps time pass and give you a bit of a sense of purpose/achievement.
We do try to get out once a day when the weather is ok - the fresh air does help but I can understand that’s not much fun when it’s painful for you.
Babies change quickly and in a few months time I think things will look very different. Try to embrace the changes (I try to see it as an adventure rather than being terrified of the overwhelming responsibility) and look forward to sunnier times ahead - your little girl will grow and become more interactive, the weather will get better and at some point all this Covid madness will come to an end. Whatever happens I feel confident we will have more freedoms/things to do over the summer, at least. If you’re planning to go back to work at some point things will be very different then too, of course.
Sending unmumsnetty hugs - becoming a parent is a huge transition and I’m sure you are doing a brilliant job. As long as everyone is fed and warm at the end of the day, that’s all that matters. Hang in there and believe it will get better, you’ve got this.
