Your font size and colour are blowing everyone away!
A current source circuit is simple and millions of them and descriptions about how to make them are on Google.
Nobody can help you since you don't specify the most important requirements such as voltage and current, nor how much they vary.
An ordinary 1M resistor can supply a constant current of 100uA to a load at 1V, from a 101V supply. Is that what you want?
First of all, I dont appreciate people that use swear words, especially when it is in a post. Secondly, Black is the colour to be used, not green, blue, or red. Black is the easiest colour to read. Thirdly, you need to specify your input voltage range, and what current is required.
This is a constant current 10 mA source. R3 is the load. If the load has a positive temperature coefficient, the power in the load will cause the resistance to increase which causes the power to increase- etc. - etc.
Huge sketch with weird values for resistors (400, 4k).
Do you think that only 10mW will cause its resistance to runaway?
I couldn't find its datasheet, but if it is anything like a 2N3904 transistor with a thermal resistance from junction to ambient of 200 degrees C/W, then with 10mW it will increase its resistance with a 2 degrees C error.
