1 year sober but struggling

I've been over a year sober now since going to therapy, I smoked weed and nic and even turned to huffing chemicals(that's when I decided to stop and get help) I struggle from depression and I've been doing really good recently but with being stuck inside due to winter my depression has come back hard and I'm having a tough time. I really want to smoke some weed, just to calm me and ease any stress but part of me is really scared after working hard to stay sober. I'm just confused and I have no support to turn to for advice
