Please understand that every legal action has a time limit, commonly known as a "statute of limitation", and if the action is not brought within that time limit, your cause of action is lost. Vandalism to your car is generally not your landlord's responsibility, unless you can prove the landlord knew your specific car would have been vandalized but did not take any steps to protect your car. If some condition in the building has caused damage to your health, you need to find a personal injury attorney; for that you need to establish damage to your person, and the amount of rent you paid has no bearing on your claim. Be sure to consult your own attorney to protect your legal rights.
Yes, this would be considered (partially) a personal injury case. The value of your lawsuit depends upon the extent of your health issues. Do you have extensive medical records and bills relating to the mold issues? If not, it is unlikely you will find an attorney to take such a case on a contingency fee basis.
It is also highly unlikely you will be able to recover half of the rent you paid. Your greatest obstacle is the statute of limitations. When did you first discover you had health issues resulting from mold?

Other counsel have raised appropriate issues. You may have statute of limitation issues, and you may have problems establishing your personal injury damages unless you have medical records supporting your claims.
You also are likely to have problems with credibility and "comparative fault." Personal injury claim recovery can be reduced to the extent a plaintiff is responsible for their own injuries. You indicate that you only had a six month lease. Yet you stayed another 9 1/2 years despite these problems. A judge or jury may find it hard to believe that the problems were so terrible when you continued to stay far beyond your original lease term. The judge or jury might also conclude that if you were incurring a respiratory or other problem during that time, your election to stay in the premises for another 9 1/2 years contributed to your health problem.
It seems unlikely you will find an attorney willing to take this on a contingency basis unless your medical problems are significant, documented, and arose in the later part of your occupancy.
