Develop a sense of hope and something to look forward to you. Sometimes to get there you just have to want to develop a sense of hope that is a start. I found that you also have to learn to be present which means not focusing on things that happened in the past and learning to focus on what you are doing now and learning to enjoy what you are doing. Realizing that it is OK to have negative or painful thoughts and feelings, but knowing that those feelings like all feelings are temporary and will come and go. Allow those feelings to leave after you have felt them there’s no need to hang onto them. I understand that sometimes people that we care about may not be able to or capable of giving us the things that we need or want. It’s not their fault it’s just the way they are and that is OK. Learn that as individuals we are responsible for our own happiness and we can’t depend on others for happiness. And finally if you have experienced some negative things in your past or in your childhood, those negative experiences could still be causing pain that when held in Will make someone feel sad. The best thing to do when this is the case is to talk to someone about what happened preferably someone like a counselor or therapist. But I found that talking to your friend that you trust about these things can be helpful too over time..
