Thanks for sharing and I have been in the similar situation before twice. The never-ending feeling of uselessness, stagnation and helplessness sucks real bad. and after a while I (re-)discovered the power of charity and routine.

You don't need something grandeur. Sometimes a routine of 5 minutes in the morning works. Write down the one thing you can do for others of the day that you can definitely get it done, and before you sleep you cross it out or not, and write down 1 small thing to be grateful to.

For example:

In the morning I wrote: I will say thank you with a smile to a random cashier in the supermarket when I do grocery.

At night I should be able to cross it out. Even if I cannot it is nothing to beat myself with. I will add 1 little thing to be grateful to, as small as able to post on HN works too!=)

Hope you can recover soon and regain your sense of self-worthiness soon. After all your are not (only) a learner and problem solvers. You are more than that =)
