Epicurism would also fit.

You read into my mind
I see stoicism coming first though,
as a necessary step, practically speaking, to exchange our early solitude cycle with another one. So my advice would be: don't leave stoicism until it has been understood as self-confidence by you and by the rest of the world and you start to make contacts.
Because stoicism is a bit simple, it is cheap to lay the foundations where the first traces of self-confidence will grow. It will be a good ground that favors interaction not because of what we think, but because of how we behave in front of the eyes of the world.
Because stoicism is a bit naive, our first natural interactions will allow our perception to gather, and our mind to process. We will naturally understand and soften, we will slide in the direction of Epicurism witch is less black and white and require a bit more experience of life.
