Is it weird for just the sight of a knife i used to used to cut myself with bein!

well, i know if you're a cutter cutting can bring your serotonin through the roof, since that's one reason why it's addicting, and i don't know of too many ex drug addicts who wouldn't feel the urge to do drugs if they saw the drugs in front of them.

That isn't unusual at all. If your family is aware of your history, perhaps you could ask if they could put the knife away somewhere for a while, maybe get a new knife? I know that for a self harmer the object with which you do it can gain some sort of significance, so while for everyone else a knife is just a knife, for you it acts as a triggering reminder of your old habits.

It's great that you are getting professional help. I urge you to hang in there with it. It can take a bit of a while before you start noticing the difference, and it takes quite a lot of work on your part as well, but it should start helping fairly soon. If you don't notice anything, perhaps you could go discuss medication with a doctor?

No its not weird. My memories are the closest things to me and if u see something that brings back bad memories it can be really stressfull

throw the knife away

You should do some traveling. Changes in scenery always help people when they feel down
