I get you, it sucks how the people who care and that we trust are also the ones we hurt most easily. Im sorry you had to go through that, hopefully it's a lesson learned, right?

There's nothing wrong with being alone, you have to learn to enjoy your own company first so you can feel comfortable around other people. It is still a struggle for me, that's why I need to be alone so often. But hey, life is a journey, not a destination, it's a constant learning process.
Wishing you the best xx
