Cultivate faith. Read good literature and watch powerful films, interest yourself in other peoples' stories. Understand that we rise and we learn; you cannot fail to see this in other lives. Empathy in the struggles of others plants seeds in one's mind, plants strong kamma for good.
Relax and follow your breath when you have space and stability to do so. Spend time close to nature; it's really worth it, you know, when you maybe have to spend an hour travelling to get out of town and you can't face it? It is worth it, even if you settle for a walk in the park.
I noticed in another post that you have problems with booze... everytime you want to drink, remind yourself that it is only a slight, temporary respite, and that you are developing faith in a complete respite. If you still drink, so be it, just keep reminding yourself, and notice the unfindability of true respite when you are drunk. That's how I stopped drinking, and I have been sober for seven years.
Hope I don't sound bossy. You'll be fine, maybe just not as soon as you would like to be, or maybe you will be fine tomorrow, this evening, thirty seconds from now
. One can't know anything except that suffering is impermanent. That's the truth, and I stake my life, my soul, my billion vulnerable nerve endings on it. So practise trust. That should be your meditation.
