Dealing with a Brother's Addiction

Recently had my appointment with my Dr., who gave me an anxiety med. for only when I need it to help prevent my rare episodes of disassociattion. Thing is sometimes they just happen with no warning. I am currently going to school, am a wife, mother, sister and so on. Anyway, I recently had to kick out my brother for drugs and drinking. He has been staying at a shelter and the requirements are no alcohol or drugs. Well the other day I let him come over because he said "I need to fill out some applications on Indeed". Well he also asked my husband if he could take him to these apartments to give them the information they need to get in. Afterwards, he came back almost 2 hours later and brought beer in my house. I am so angry! He confessed he has done it three times since he moved out. I know it is a lie but anyway, he tried to play on my husband's heart strings, saying he thinks he might be kicked out. The place he is at also requires 10 hours of community service somewhere. Well he hasn't done it for the month. Yes, he has been there for a full month! My husband told him well if you get kicked out you can stay in the garage. I told my husband No! Anyway, I feel bad but he can't, he brings the household down and I also need to protect my family. I told my brother he can't stay in the garage, and he needed to learn from his decisions. I feel so overwhelmed right now with his antics!
