Point of no return

Point of no return, must go forward no matter how big is the obstacle.......thinking back, why do I venture into this path? I am at the lower side of mood....after a month of hard work scattered to ashes...ashes to ashes...hu hu....must remember it is a learning process.......but the demotivation is hard to accept, and I keep questioning myself again, can I continue with this, am I able to perform....maybe it is not my cup of tea, but it is too late now to withdraw, too much has already been at stake.......I must go forward.......I have invested time, money (although I am fully supported in this), and the most important thing is sacrificing my clinical experience for this, I must go forward....forward is the only way.......Ya ALlah, assist me in this, ameen
