The wait is horrendous so I completely empathise with you.
I was approved in the August and it was either the following June or maybe even the June after that before I was matched with my child. It was excruciatingly painful whichever it was.
Linkmaker was a real bone of contention as my SW was very against it. Plus what people describe here of not getting responses, or being one of so many. But, friends of mine were matched with their child there, so it does work when it works, if that makes sense.
What I will say though is that as painful as that wait was, I wouldn't change a single bit of it because if ANYTHING different had happened along the way I wouldn't be mother to my amazing child. I'd be a mother, but not to this child, and that doesn't bear thinking about.
I would also say when you are approached, because you will be, try to stay true to yourself and listen to your gut. I was approached with two links, neither of which sat right with me for different reasons, yet it felt very pressurised kind of like 'you've waited all this time, you must say yes to any child that's presented to you', obligation and pressure I guess that's what I'm saying I felt. Plus, I was terrified of saying 'no', for so many different reasons, but thankfully I did. It wasn't until I was approached about my child that every single doubt I'd had the last two occasions melted away.
Try to remain as objective as you possibly can be (soo difficult) because you have to be 100% certain that you can be that child's parent. I had zero doubt with my child, your gut will guide you if you listen to it.
Good luck xx
