How to get mental help ?

Hi there everyone. I'm wondering what steps are in getting mental help in Ireland. I already went to GP and they booked for a blood.test to see if there is something wrong with my body first. Last week I got nocturnal panic atack and since then already 7 days I can't sleep, I sleep maybe 2 hours when my body fails. Today was my worst. I smoked cigarettes after 3 months of not smoking and my anxiety feels like i'm going to die. Money is the issue unfortunately, so affording proper therapy might be a challenge. Considering that I'm not that familiar with how the things work out here. I appreciate anyone with any information 🙏
