Worried about my use

Started using it about 2 months ago when I started seeing this girl who sniffs quite a lot ( not unheard of to finish 10g in a night ) I haven’t gotten that bad but I can’t remember the last day I didn’t use it I used to smoke about a 1/2 ounce a week and have now basically stopped but instead get through about 6g of k a week instead it helps with my anxiety but feel it also worsens it when I’m not sniffing my friends have started to think it is becoming a problem but I don’t want to stop
