Why do I get stoned every day

I (21m) graduated in May and I’ve been working a job I hate. I’ve found that the last few months I take an edible every day and if I don’t I go maybe a day or two without taking a edible. What’s wrong with me? It’s not that I think I’m addicted (though there are times I do feel I am) I just feel so stressed out all the time. My girlfriend gets stoned a lot too. Should I stop? Or at least limit myself? Does anyone have tips on how to do that successfully?

Edit: thank you guys for all the help and advice. I really appreciate everything!
