I have one advice.

Cause of Problem ( Let me know in comment if this doesn't apply to you ) We get depressed because of lots of hopes and expectation, the main we are looking is getting to end as fast as possible, without enjoying the process in itself.We are looking for goals ignoring the values and process it takes. I tell you process and value is more important than the end goal. The main function of goal is what you become.

The simplest advice is keep grounded in action. Start small , do small action and build upon the small steps to bigger ladder.

You are feeling depressed because all the while you have said to yourself you are great hacker and when you start something you are not able to complete it, hence the spiral of de-motivation. Focus on action and work, eveything else is secondary.
