First, it is not uncommon for folks with severe dependency on gabaergic substance to struggle with what you are experience during the first six to twelve months of abstinence.
The thing is though, your emotions are there, they are just very difficult for your conscious mind to perceive at any given time. Have you tried cultivating a mindful awareness meditation type practice? It would certainly help enable you to get in touch with your emotions.
You might also want to look into NMDAr antagonist therapies, like using ketamine (it has been shown to be helpful in treating those with severe alcohol use disorder, which is very similar to what you're dealing with), or utilizing some other kind of empathogens? Something like ayahuasca might help jumpstart your sense of connection with the world and reduce the anhedonia you're experiencing.
I'd strongly suggest looking into NMDAr antagonists and trying those in terms of a pharmacological approach. Behaviorally, I strongly suggest you check out mindfulness meditation techniques and develop your own practice. Exercise, healthy sleep patterns and a balanced diet also can help a lot when it comes to improving your mood. Same goes for making sure you spend enough time with people you enjoy the company of (isolation is the near enemy to recovery).
What kinds of things are you doing in your everyday life to increase your wellbeing and prioritize your health? Have you thought much about what you want your goals to be regarding your life and recovery?
