>I often talk to myself
Talking to yourself isn't a sign of mental illness long as it doesnt interfere with your daily life.

>are alter egos a form of tulpa?
Depends on your definition of an alter ego. Tulpa's are often consedered a class of mental entity by the paranormal community. They are a construct of thought that have the ability to think independantly from their host. 

>how do I fuse with mine?
This greatly depends on your personal situation. If you consider how you currently identify a problem, a doctor might be the best person to ask.

On a seperate note:
Through all of my research, I have found that all Tulpa's go though a healthy life cycle of sorts. During a point of need they are born, over time they should help console and care for their creators, then when the users need is fufilled the split consciousness is unified back into one. During trauma, this is extremely usefull as bad memories can be protected or straight up wiped with your Tulpa.
