Does alcohol really numb your emotions?

No. The exact opposite. Iv known some serious alcoholics in my life and it never numbs you. Its like putting a bandaid on a bruise. You feel like shit about your life so you try to cover it up with good feelings and carlessness. Same concept as drugs. Accept some drugs might actualy numb you. Most people just end up digging there own grave by repeating the process rather than directly fixing the problem because they feel too depleted from the damage to have the will power to even try to climb out of the hole they made. Eventually you grow a tolerance to your vices and its all you know until your body can no longer handle it.
