Worried about infections

When my SPD comes back (i was doing so well for a good while :/) I often get skin infections, the worst/most painful one being the area around my toenail.

Does anyone else ever try to get an ingrown nail out, and end up just going ham with it? It never ends well, but neosporin does the trick. But I am worried about the effectiveness long term if I don’t get my act together, and picking is like a reflex whenever I’m going through stressful times. You would think my prozac would help.

Thanks for letting me get this off my chest
