Crawl, drag yourself if you have to. Everything seems black and hopeless but it does get better.
I completely know what you mean by thinking that there is no point. I recently, as you know, went through similar and it was a dark dark time. I think only now a couple of months down the line am I finally beginning to have some days where I feel alright.
I'd send you hugs or some of that shit that internet wankers say but it's not my style. Sending you good vibes instead :0)
