Life

I don't really know but like i feel that something bad is gonna happen to me and idk what it is i've done some bad things but lifes just to good and i don't trust it. I don't really know why i feel this way but i just do it feel like my life is gonna come crashing down again and i don't think i'll be able to recover from this.I have a loving gf who cares alot for me and  will let me do anything but if and when i try i just feel wrong and there is nothing bad about it and she enjoys it but i just never feel right and idk how to solve it but yea :(
