I think many people go through similar phases in life, i actually think most of us do. And i believe the more ambitious one is,the more one become incline to those kind of feelings.Two things to watch out for are : how long does it take you to snap back to your regular self, and do you learn anything from those dark moments. Has to what to do ? I don't have any solutions but i can offer some reflections of my own having been in that dark hole myself a lot of times. First let's talk about your inner world. I don't know you, and i don't know the struggles you face, but independent of your external conditions, there is a large body of "technics" on how to deal with and manage negative emotions ( lookup self-regulation in emotional intelligence for a start). Beyond that, the idea of "emotional hygiene" has been very helpful to me.Much in the same way that feeling tired all the time is usually a sign that your body is missing something, experiencing long period of negative emotion might be a sign that your are not taking care of you emotional system as you should. Some people mentioned hanging out with friends etc...A sense of belonging is very important (even for introverts) , but there are many other aspects (Ask more questions is you want more specific item as to what to do ). I also get from your post the impression that your self worth is somewhat attached to your success... A lot of us feel this way, and that's a very dangerous way of valuing one self. Now after all that emotional sweet talk, the fact remains that emotions do usually contain a kernel of truth. i think the gist of it is that your are not happy with the results your are getting given the amount of efforts you putting in. The reason for that might that your model and assumptions about success and how to be successful are not accurate as they can be. In other words, what you experience as "luck" for other people, might not really be luck as much as a chain of consequences that your model cannot explains. You mentioned someone getting a cheap housing, maybe it was pure luck , or maybe that someone has better soft skills which translated to better/bigger social network which resulted in him/her being aware of more housing deals; and more housing deal combined with better negotiation skills resulted in a good deal.So instead maybe you should be thinking "i need better soft skills". So maybe this is the time to reevaluate some of your core belief; You seems to be focusing on "hard work" as the main variable for success...But smart work,soft skill, opportunity and leadership are all equally important. How are you doing on those fronts ?
