Where should I start?

So im in quite a bad place with confidence, self esteem, stress in my family life, lack of motivation etc. Ive always been very into self help and trying new strategies for various problems in my/family life but after many failed strategies I have no motivation to try new ideas now as I expect them to fail. My head is also fried with all the things I need to work on that I dont know where to start. For example I feel it would be wrong to launch into some plan to keep me motivated with work when my self confidence is in the gutter.
