I'm sorry you having such a difficult time. Hopefully having come here to PC can be of some comfort & support. There can be a lot of support available here. The more you post, & reply to other members' posts, the more a part of the community you will become.

You didn't mention if you're seeing a therapist or being treated by a physician for your depression... or if you're seeking work or just not able to be employed at the present time. But, hopefully, you have some things going on that can help you with your depression.

Here are links to some articles, from PsychCentral's archives, on the subjects of how to prevent a relapse into depression as well as a couple on the subject of loneliness & how to build a circle of friends. Perhaps some of the information in them will be of some help:
