Break in sadhana

Dear sir,

1. In one of the previous posts, I read that one shouldn't take any breaks in sadhana for random indulgence may lead to problems and the practice may lose its effect.
I had to go outstation as a part of my work for 1.5 months, i tried my best but couldn't continue sadhana properly and in the last 25 days or so, i completely gave up sadhana altogether due to heavy work pressure which disrupted my entire schedule.
Now, I'm afraid that some harm may befall since there was a gap.
Will it be harmful to start?

2.from past few months, I'm having problem in thinking, I have a kind of blocked thinking, irrational thinking, sometime without any substance which was not the case 12-24 months back and as a consequence, my communication is also getting hampered and people hardly understand what I mean (this could be evident from the way this question is written) to say Could you please tell me what could be the problem?

I will take a firm resolve to never give up sadhana irrespective of situation. Is this much enough?
