Activist Burnout leading to Anxiety/Depression

Hi all, not sure if this is the place to post this or not but here goes.

I'm politically active (on the progressive side of things) and I am really, really, really to the point of being worn out and just distraught with the state of the world. I'm still going and doing whatever I can but I'm really finding it taxing on my mental health, exhausting in general, and, honestly, I'm finding myself getting to the point where I really just don't like people in general and I feel like that's a big red flag that I need to check myself and at the very least find a place or a person to vent to. A really great listener here (Ben19-highly recommend) helped out a lot by giving me an ear but after talking with him I really think I need to find a support group, official or unofficial, and probably a site or something that posts nothing but good news to remind me that the world isn't totally going mad around us.

Again, I don't know that this is the place to post this or if I'm just chasing smoke here on this one, but if anyone can point me in the right direction or is going through similar stuff I would very much like to hear from you.
