Stuck in a rut

Male 37 from UK, lost my dad 4 years ago and I know it’s not an excuse but I’ve been drinking everyday since and smoking ciggies a lot more too. I’ve always liked a drink but I now drink every night between 5-10 cans of lager luckily weak stuff not strong. I just don’t know how to stop now to be honest, I’ve got myself into a routine where I drink every night until midnight and I’ve put on weight, I’m tired, grumpy and just feel weak. My hands are always hot and sometimes puffy my back hurts sometimes just falling to bits. I know I can quit drinking because I done a month clean in July but have just gone back to it since but it’s the smoking too I need to quit but can’t. It’s so difficult, has anyone ever managed to quit both and if so how and what are your benefits health wise that you have noticed as I can’t keep doing this. Sorry for the long post.
