Hello, and welcome to the forum!
There are a couple different kinds of cravings for opioid addicts. First, we have the physical cravings that plague us when we try to cold turkey off our drug of choice. Second, we have psychological cravings in some circumstances. For me, for example, the day I was induced on suboxone, I went from thinking of nothing but getting my hands on some oxycodone to being amazed that I could think of other things besides drugs. I've been on buprenorphine now for over 6 years. There have been times that I think about what it would be like to get high again. Fortunately, that doesn't happen very often.
My point to you is that you are probably experiencing psychological cravings. A lot of us have deep seated pain from trauma, painful memories, long term depression. On suboxone, you still have to deal with your addiction. In fact, if you don't, someday you may come off suboxone and you will be right back where you started. I want to let you know that it's not unusual to want to go back to that warm cocoon where you feel happy and so content. But you have to question why that still appeals to you.
I have two suggestions. First, find an addiction therapist who is well versed in cognitive behavioral therapy. CBT is great for changing harmful thought patterns. Second, find a SMART Recovery meeting near you or online. Here's the link for finding a meeting:https://www.smartrecovery.org/local/
I like SMART because it gives practical help and ideas to addicts. They have no opinion on people who are on medication for their addiction.
If these first two ideas don't work for you, you might need to find an intensive outpatient program to get your head in the right place. You will be much better off if you are working on your recovery.
