Hoi,
1. Check your PMs
2. Lots of people have had symptoms like you if they have been through a period of excessive stress. They made a full recovery and went on to embark upon or continue successful careers in many different avenues.
What you want, reassurances that all will be well, will be impossible to give as everybody is unique.
Unfortunately a few people will continue to have a recurrence of the symptoms which you describe and the road to an ATPL and a job is not without its risks of failure and stresses. It is difficult if not impossible to predict those who will have had a single episode and those who will get recurring problems.
Having a previous history of a 'breakdown' is not necessarily a bar on getting a job in the aviation industry, after all what matters is having the appropriate ticket and matching medical, but this will very much depend on what the market is like.
So in the end you will have to take a close look at yourself and see what you want. Arguably someone who has been successful in paving the way so far by working this hard will succeed in finishing the project off.
Best of luck
FD
