6 months after breakup and I feel mentally ill, I need help ...?

I am so heartbroken from a breakup that happened earlier this year. For almost 6 months now I have spent everyday miserable. I can't even get things done. I dream about him all the time, he lives in my concious and sub-concious. I wake up sad and wanting to cry because he is the first thing I think of when I wake up. I am not interested in meeting any other men because he met my criteria in every aspect...all the way from the shallow physical to the chemistry! He is all I want and for a while I was texting and calling him non-stop but now I try to limit it to avoid ending up with a restraining order, lol. I miss him to death and truly sometimes want to die. I am 25. I don't have insurance so a psychiatrist is going to cost a ton. Should I go to a psychic ... someone? I feel mentally ill. Don't tell me I am young and have my whole life ahead of me as those may be uplifting words it does nothing for me !
