Spiros if you are anyway like me, these emotions you feel will be there for a while.
At some point you will get so low, that you will end up letting all your worries and concerns go, just like you said in your OP ..."and just laugh about it all".
But ultimately I believe those feelings are there to guide you in the right direction, even if you can't see it right now. So you very lucky that you are into Personal Development, because people that are into PD become highly aware about things and their purpose is to discover their true self.
What I would start do and what helped me, is to verbalise my concerns that happen to me on a daily basis.
So if I had a bad day at work, I would drive back in my car (alone) and verbalise out loud what I was feeling. So it be something like, "I hate it how Jack treats me like an imbecile in front of others at work, why does he do that to me?", then you might say something like, "you know the real reason I am annoyed, is Jack is really not that smart, he is lazy and does no work, but what is good at is manipulating people to believing he is good at his job, so I am happy that I am a better person than him"
When you start verbalising your thoughts out loud, your confidence and your convictions grow and you start to see things for how they really are, and you believe more in your intuition and yourself. You become stronger and closer to your true self.
Well I would suggest looking at the book Refuse to Choose and see if any of the writers suggestion resonates with you, but before I read that book what really made it clear that I was enterepenur was Yaro Stark's blog
Internet Business Blog - Entrepreneurs-Journey.com by Yaro Starak when I started listening to some of the interviews he conducted I resonated so much with what a lot of them were saying. A lot of them said the same things that I would say to myself...never good working for others, always had lots of ideas but got bored of them, had all these skills but never really utelised them yada, yada. Actually shoemoney's interview was the one that did it for me, his personality in some respects was a lot like mine, like he wasn't great a school because he was only interested in things that interested him and that he was a very hands on person
Podcast: How Did Jeremy “Shoemoney” Schoemaker Get To Where He Is Today? - Entrepreneurs-Journey.com by Yaro Starak Through that whole interview I was going "OMG that's me" and it was a like a light bulb moment.
I've always had entrepreneurial tendencies I just never really embraced them or verbalized that that was something I would want to do, as I just thought it wasn't possible to do that sort of thing.
Since verbalising that I am an entrepreneur and putting my ideas into action, I have had the best time. I get so excited seeing my ideas turning into actual projects. Everyday I wake-up focussed on my ideas and putting them into action and at the end of the day I am still excited. This is what gets me going.
So you can change, I am living proof...it's just wether you are strong enough and wise enough to take the journey...most people are not, those that are...well are really lucky
