Here are a few things you might consider that would have you interact with people in real life.At each of these you need not participate at all - at least not verbally - and it would get you out of the house rather than further isolating yourself.

Find a club of interest to you. A book club is a great idea. You would be welcome just to attend and listen. Any of those I have been to do not pressure everyone to talk. But it would be a great way just to be around people - which is a really good idea for those of us with a mental illness.

So, what about a support group? These too do not require one to talk. Again, this would put you around people only in this case they are akin to yourself.

Art class?

I realise you are looking for on line social support here but I strongly recommend getting out as, self-isolation can be detrimental to our mental health.
