carrier bicycle problem, help needed
so i built this creation, it has rear end of a bicycle and front end is carrier kinda thing, pretty usable for transportation of lightweight things and so, but i have one problem, whenever i ride it it is very hard to steer, wheels are adjusted for toe in and out good and it lifts front wheel in corner like it wants to roll over, also when its stopped it will sort of collapse at extreme steering angles, if i fixed these things its gonna be really good carrier thing, looking forward to replies and advices, also hi im new around here and it doesnt let me to upload a photo

Cycling with cargo is problem. Your solution is similar in some ways to some existing designs, but it differs in the bike's geometry. The steering axis is the centerline of the fork. The wheels look to be too far in front of the steering axis. Your bike reminds me of the Worksman Front Loader.
This picture is from Worksman's website.
With this style of bike the steering axis is under the cargo box close to the wheel centerline. The whole cargo box is part of the steerable front similar to your bike. I don't know if Worksman places the steering axis right in line with the wheels or slightly in front of the wheels. If I were to guess, I would think that the steering axis would be an inch or so in front of the wheel center line.
It looks like you welded your bike together. If so, you have the skills to make the modifications to make it similar to the bike shown above. That will solve your steering issues.
Keep the pictures coming @kirovecbiker as you continue to work on this bike. This looks interesting.

Can't tell for sure from the picture but it looks when turning you may not be allowing the inside wheel to turn sharper than the outside wheel (i.e., ackermann compensation). Maybe you've done that and I just can't see it under the front cross member.
EDIT: This video (starting at about 2 minutes in) gives a very simple explanation of ackerman geometry and why it is important:
