I'm not a doctor, dont even play one on tv, so I'm always hesitant to share medical knowledge.
I am aware that most doctors are clueless
when it comes to addiction. I see why they have addiction specialist. Nothing worse then telling a doc how your feeling and they just throw generalizations at you or a one size fits all solution.
ALL that being said, there are some decent ones out there, you just have to look I guess. Ive been emailing an endocrinologist from California that has been giving me som really good advice on supplements to help with my diagnosed adrenal fatigue.
If you dont have some major stress in your life causing your feelings ( like an healthy relationship) and you just feel crispy for no reason it more than likely chemical. Even when we feel "normal" it is a right balance of chemicals/hormones in our body that allows this. An out of whack thyroid, low testosterone, or poor endorphin production are just a few things that can cause you to be "depressed'.
I would suggest you get some simple test to find out.
This is if you have been plagued by this for sometime. If this is related to a recent stop of drugs (especially opiates) what you are feeling is probably "normal" as I feel the same. It takes time for our body hit reset button on out of sync endocrine system. I know it sounds simple, but we just have to recognize it for what it is and monitor how we feel.
Trust me I know it is tough and having to make decisions on your mental health with a messed up brain ( for lack of better word) might not be best decision. If your mental state is becoming debilitating I would see a doc.
If it is just nagging I would hang in there. Just my opinion as how I'm approaching it.
Good luck and try to find something to make you laugh/smile if possible for temporary mood change.
