@JLG21,
Me, I would prefer to be by myself, but you know what I actually like myself so I don't mind my own company.
The thing is - if you stay with this friend group - you have a greater guarantee of being alone since they are not including you. You have a better chance of not being alone if you find people who are good to you - they will include you - you will have more enjoyment being around these other friends.
Yeah it might be a bit uncomfortable to try and reach out to some other people, but the results appear to be much more positive.
