I've had a lot of therapy over the years but it was only when I learnt (through the therapy) to work out what my feelings and emotions were, that I could start to work on them.
Most people, entering therapy, have no idea what it is they are feeling and it takes a lot of work to be able to identify them. Only then, can you work on managing them and making them less of an obstacle on your life. You can learn skills on how to make them less painful but you will need help (professional) to do that.
I strongly recommend speaking to your GP about counselling. I know its nerve-wracking but it will be worth it.
