@Flower88 . I'm currently in a similar situation. Except for the dating part.
After about 2 years, my depression has finally gone. During that time though, I isolated myself, and only have 1 friend I see or hear from. I'm lonely. But struggle to join in groups or volunteer organisations.
Today, I just dropped off my form to join WellWays, a group that supports those with physical and mental illness to join in and have a full life.
Now obviously I haven't started yet, so I can't tell you if they are good or not. But I hope they are good.
Could you find an organisation like this near your area? It might just give you a head start. And help stop the loneliness.
Just a suggestion. I wish you well.
