I've been using weed to self-medicate my anxiety for years. How can I stop this behavior?

I've been struggling with my anxiety since I was a kid and ever since I first smoked weed in highschool I knew that I was on to something. For years I've used it to either forget or attempt to curtail my anxieties. Now, I just started a new job while also going to school and although it helps sometimes I fear it's beggining to hurt me more than help. I'd really like to stop using marijuana to medicate my anxiety because I'm tired of feeling like I need to smoke everytime I get anxious. Has anyone on this sub been through something similar? I'd really appreciate any helpful tips.
