HOA Dispute — mold in apartment making family sick

I'm dealing with a situation and need some guidance.

mold in apartment making family sick. I've been dealing with this for about 2 weeks now and the situation isn't improving.

I have been renting for 8 years. My monthly rent is $1,398. I have a written lease.

Should I hire a lawyer for this or try to handle it myself?

Not a lawyer, but I have direct experience with this.

I ended up filing with the appropriate government agency, which cost about $4-8 but saved me a lot more in the long run.
