Please don't apologise and it isn't a rant. I understand how you feel and you are in a tough situation.
You can say whatever you like here and I will be here to listen whenever you like.
It does feel really weird being left out and feeling like the third wheel, as you don't know how to respond to the other people. People are really stressful, you never why they are changing and how to respond to them changing. Before remote learning, my friends would do the same thing and during that time I thought leaving the group might help but it didn't, as they joined the group and walked with us, they were annoyed with me though.
I understand how you feel about your close friend leaving and barely talking with you. she should be trying to make the most of her time she has with you and its not fair how she is barely talking to you. But maybe, she also afraid that she is leaving and she may be afraid of losing friends and is trying to make as many friends as she can, but we don't really know why she is doing it.
That must be really frustrating how they are posting about playing and face timing. Its really not nice that they are doing that and you are part of the friend group and they should ask you if you want to join. Maybe have a go asking them that you would like to hang out and see how they respond?
It's really good that you have a friend who you can talk to. I understand that it is hard to change with having multiple friends to having one. what things do you can go wrong?
It is really hard to find others and make friends, I still haven't found anyone who I feel comfortable with at school. You are right, changing schools can have benefits, maybe you may find close friends there and like you said that there are more opportunities there and it is really hard to change schools and leaving everything behind and starting fresh. I moved schools in year 7 and i didn't enjoy the first term of the year because i missed everything from my old school too much, but after a while, I liked the new school better than the old one.
I think you should what you feel comfortable with and you think is the right decision. Maybe you could talk to the school counsellor in your school and they might help?
How are you? How has school been?
Are you still in remote learning?
I have to go back to school next Monday.
Thank you for being such a good friend and I hope you have a wonderful day
