Challenges in doing phd.....

Why I said too many 'dugaan' in this journey..maybe different person different perception on 'dugaan' or challenges....for me ..my challenges for this journey.....:

- always feel lazy when the study time come....
- tendency to being sleepy especially after my girls sleep in the night...hardly effort to stay up or burn in the midnight oil..
- not in good health either myself(at the moment~~yes...I got headache on off on off, cold and hardly to breath), my spouse or girls
- lots of things to do and sometimes don't know which is the priority....
- home sick feelings
- nobody never understand my situation...only family understands me(mom and my sister) but only phone call my bridge with them not face to face(not use skype at the moment)...that is challenge!!!!!!!!
- hardly consistent with the planning....so worry with this challenges
- don't know how to struggle..if I can, I wish to spend my phd time almost 12 hours per day...but normally plus minus 5 hours only....

- normally when I think about my research very deeply after perform solah, I will cry as much as I can..because I'm not sure either I can finish this journey or not....just 'tawakal' to Allah and feel very humble to Him and ask to Him the maximum strength to strive my journey...amin

sometimes I feel I can depress and feel to quit with this journey!!!!!!!!!!!!!!!!!!wallahualam.....anybody can help me??????
