Hello NothingLeft, a courageous effort in posting your comment and from you've told us my heart drops for you from what you have and are still trying to cope with is certainly enormous.
Your ex took everything from you, and whether or not she still owns them or used them for her drug addiction is not for me to say, but it has left you in bankruptcy which I am so sorry for.
Can I suggest your doctor review your medication and tell them why you are asking, also ask them about a medication which stops the craving to take drugs and/or consume alcohol, these combined with counselling could be the answer you're looking for.
We understand how you are also thinking about the lump under your collarbone and realise how worried you are, but it's better for a doctor to tell you now, rather than in a few months time.
You have so much to cope with but let us try and help you now.
