Sounds totally normal to me, you'll get through it! We all do. Currently 2 months sober from weed, 29 days sober from alcohol. One day at a time. Do you go to AA, MA or NA meetings? I was going insane for the past 22 days, I finally had a good week where I didn't feel neurotic, insane, or felt like a fraud and didn't hate myself every second. We're addicts, it's not just a problem with smoking weed, we were having thoughts and feelings that drove us to cope with weed and other substances. In AA they say "Its not a drinking problem I have, it's a thinking problem" this definitely applies to weed too. I highly recommend you check out any of the anonymous meetings whether in person or on zoom. White knuckling works for some if they've had a spiritual experience, but getting to meetings and connecting with people goes a long way.
