I am not trying to be harsh, but it sounds like you have more of a maturity problem than anything else. Did you not think about the airline pilot lifestyle during all the grueling months you worked getting your 1500 hours? After you left the first regional, did you not expect more of the same feelings you had when you joined the second one? But maybe you had a change of heart, I can understand that. This type of flying is certainly not for everyone.

With that said, what upsets me the most is that you did not think about the financial consequences to leave both companies without having a plan B, which is now why you're back and looking for a third job. This is something you just do not do. At least have a backup plan that you can go into. If I were you, I would take step back and really think about what you want to with your life. Quite frankly, it doesn't seem like commercial aviation is the path for you. It is time to grow up and figure out what you need to do going forward.
