I think I messed up my pets life

I had 4 bunnies, me (19f) and my partner (20m) were renting and got two rabbits after getting our first two rabbits thinking what could go wrong.

we had had the first two for around a year and thought it would be fine. the four did not get along. We had had the original two for while we were renting and we were very close with them, the other two we got were happy together but couldn’t get along with the others and were deeply unhappy in their environment it seemed no matter how much time I spent with them and how much space they had it seemed being in an area with other rabbits were making them unhappy, when I put them into a different room they were still not happy and I couldnt give all four the most attention and love they deserved.

I tried different things and different solutions until I felt like my only choice was to give them a chance at a better owner who can give them a lot more attention and can afford nicer things.

so I did the best thing I thought and sold the newest two rabbits to a good quiet family with no other pets and no kids a lot more space and more money.. I gave them a cage, two birth certificates with their vaccine certs and their favourite toys, leashes and food. I text them after to please send pictures and to give any updates

Though it seems I have been blocked on everything after they got my two bunnies, It has been about 5 months since I sold them. I wanted to find a way to contact them. I’m scared they are doing something terrible or they don’t want them anymore and that’s why they blocked me… they seemed a lot more well off than me and could give them a way better life but what if they’ve done something terrible and I messed them up all because I couldn’t handle work and four rabbits at the same time…

If they don’t want them I would happily take them back and figure out a different solution for them!

my other two bunnies are very happy and have a lot more room and are really enjoying life which I’m happy about but I can’t help but feel so sad when I think of my two little babies I gave up whenever I see their pictures on my phone… am I overthinking or should I keep trying to find a way to contact them? I don’t know why they would cut contact

the family I gave them to were a good family with proof of enough room and they knew what they were doing, they seemed really happy when I met them and seemed really keen on giving them an amazing life.. I can’t stop panicking… please let me know any opinions or advice, thank you so much
