the eat veggies part is not going to do much, but picking up a new hobby if you are not too far gone already will help, not that i talk of experience of anything.
and also one thing that helps me a lot is to try and make peoples happier, i spend way too much money in gifts and cake supplies but then it prevent me from killing myself, so good overall, i think. although the downside of that is when i hurt someone it really hurts me inside, so i try to be the best i can.
oh and some doctors may be *******s, mine told me i could never get out of it without taking hard addictive drugs, that i refused to take because addictive.
