F (25) struggling with extreme anger and anxiety after quitting weed.

I’ve been smoking weed everyday since I was probably 16 or 17. I now have 2 babies and I want to be a better mother and more present. I’m about 2 weeks sober but lately I have been struggling with extreme rage. I feel like I have compressed and ignored so many emotions with smoking weed and I honestly don’t even know how to deal with myself now that I’m not smoking. I haven’t been sleeping more than 4 or 5 hours a night which is not enough for me and all I want to do is smoke a joint and have a good sleep. I have been trying to go to the gym ever night to help myself sleep and release emotions but it’s just not enough. Is anyone else struggling with intense anger and irrationality or am I just crazy?! I feel like I’m crazy and I don’t have many people to reach out to for support. When do things get better? :( feeling so hopeless today.
