What really helped me was getting a counsellor who I really felt comfortable with. It wasn't so much what he said - but more just being able to open up and talk and feel validated. Honestly, it has made all the difference.
Even now, I still go and see my therapist every so often. Sometimes every other week... sometimes every couple of months. The key is to notice how you're feeling and not let it get too carried away.
Something else that has helped is to make a list of little things that might be bothering me. A lot of times I find that there are 10 little things that are bothering me... BUT, when you put them all together - Geez, that's a whole lot for someone to bear isn't it?
