Ouch! I suggest you skip the comment above, its not likely to make you feel better! He made me cross enough to stop lurking and post!
Try not to be too hard on yourself. Remember that your patriarchal blessing is for the rest of your life - no one expects you to become relief society president tomorrow, but who know what changes you and heavenly father will make together in the next 10 or 20 years! Sounds like you don't have a printed copy yet so i'd wait for that and then have a look and pick out some things that make you feel good.
Its really hard to recognise the spirit - I've been a member all my life and theres only a handful of times when I can say yes, that was definately a prompting that came from outside me. Every body's different. What I try to do is follow any thought that tells me to do good - whether thats the spirit or my own thought at least I'm doing good! And it means I get practise, and tune myself in, and helps me to know when I am hearing the spirit.
Get some help with the depression - I know when my grandmother comes out of depression she talks about being able to hear the spirit again. And when your feeling a bit better take some time for yourself - join a book club, do some gardening, take a class, just pick something you've always wanted to do and make time for it.
