workinonit, it sounds to me that you are going through too much for you to handle on your own. Sometimes lifes burdens are just too much for one person, a young person, or at least they seem to be. There are two ways for you to deal with it. Either find someone, an older person, a life coach, or a therapist, that can get you through the bumps. Or write down the whole big picture in a journal and then break off small pieces and just deal with them one at a time.
Sometimes life can seem very overwhelming. It is that way for many of us. But for a young adult it can be suffocating. But when you choose to deal with just one issue at a time until its conclusion and then bite off another one, until you muddle through as many as you can it is less overwhelming. That is how most adults tackle their problems. We can’t handle everything at once, so we just deal with what we can, the worst or the most pressing and then we move on to the next, and then the next.
Is that something you think you can do?
