Dealing with withdrawals and change suck

I stopped smoking or taking edibles a few days ago (I can’t remember how many but definitely less than a week) kind of accidentally but now I want to keep going. I’ve been a fairly consistent daily user, always at night to help me unwind and get in the mood to sleep for probably the last 2 or 3 years. Covid took a huge hit on my mental health, I’m a healthcare worker, and I found it to be the only thing that really relaxed me enough to fall asleep. Now that I’m a few days sober, I find my anxiety to be through the roof to the point where I can’t focus on anything. A few life changes have also happened in the last month too. My dad had major surgery and has been having a difficult time recovering, I started dating someone new, and I started a new job that’s fully remote (where as before I was fully in person doing shift work). While most these changes have been great, the past few days being sober has made everything so tough. When I say I accidentally quit and decided to keep going, it was because I was able to fall asleep for the first time a few days ago without any weed and thought to myself why not see how long this goes. Let me tell you, I’m having so many second thoughts. I have anxiety at baseline and have previously been on medication for it. I also am in therapy dealing with my anxiety and overthinking. I’m starting to lose hope that my brain will never return to its baseline. I’m not even sure how much longer of this crippling anxiety I can take!! All of this change and now being sober has really highlighted to me how dependent I was on weed and it’s making me feel like I can’t handle all this change in my life without weed.
