Welcome back Tetrax! I'm so glad you posted. You can get lots of support on this site, and joining the January of 2019 class, and the 25 hour thread would be a great place to start to know other members. That may help you start to feel a little more connected, and also a little less lonely.
Do you have any hobbies? Maybe you can take a class at a local community college, or join a walking/running group. It would help you get to know people and not feel so lonely.
