Weed withdrawal

I have been smoking weed regularly for about a year and a half. At its worst, it would be 6 joints a day, but that would be rare, It was probably about 1-2 joints a day if I averaged it out.

After about seven months of smoking weed, I began to develop 'generalised anxiety disorder' looking back I always have had anxiety, but it was too little to notice and certainly too little to affect my everyday life. Since around a year ago my anxiety has gotten worse and worse, only when it began to affect my social life is when I decided to quit.

Over the last year, I have had about ten different symptoms which come and go which range from excess mucus to chest pains, to heart palpitations and even my whole face going numb. I had an anxiety attack in January in which I went to A&E and had the full works done on me, I had a chest x-ray which came back clear.

It was only in late May when my chest tightness came back that I realised enough was enough and decided to give up weed for good. The first ten days were really hard, all my anxiety symptoms came at once and I was a nervous wreck. Then for a few days things started to look up. Over the last two weeks the depression has kicked in and I'm feeling quite low, the physical symptoms have gone down, but sometimes flare up for a few hours and go away. I occasionally cough up mucus, mostly it's clear but sometimes it's a little brown, but apparently, that is the lungs cleaning themselves out.

Does anyone have any similar experiences?
