Picky eater..

I dont know what to do I'm worried and stressed i feel like my 1 year old son wont eat anything I try to give him.. he will drink milk and not eat all day, never took to purees and doesnt like to be spoon fed, if I give him finger foods he plays with it smashes it and throws it on the floor or he will eat two small pieces and throw the rest on the floor the only way I know if he likes something is he will actually keep it in his mouth and not gag but even with the things he does like he wont eat I've tried limiting his milk so he wont get full so quickly and he will eat but that doesnt work he just takes two bites and done, I've tried distracting him with cartoons so he wont throw his food on the floor and that works sometimes but he will eat very very slowly but how long am I supposed to let him sit in his highchair eating before I'm a bad mother ? Any tips? Suggestions? Are there any supplements I can give him ? Do I need to buy him specific vitamins? How do I keep him healthy if he wont eat ? Please help this momma out.
