Hi Shelley
I understand how being depressed can make you feel. I've been depressed for sometime and I do take medications which help to alleviate the depression as well as cognitive behavior therapy. My therapist does refer to cognitive distortions when we talk about ways of thinking and identifying the distortion. Beyond this I would like to say, never give up, there is hope just around the corner.
Many times I feel overwhelmed, I try to look at my problems one at a time, rather than looking at the whole picture which can make me feel depressed.
I also believe in prayer, and find myself praying a lot to see me through, as I know God does love me and he loves you too. Talking to a pastor may help.
Sometimes it helps to get out and do things with friends. Call a friend, be a friend. I've found that when I'm feeling depressed I tend to isolate myself and not reach out or talk to people. This does make me feel worse, as then I find myself thinking nobody cares, when in reality nobody knows because I haven't reached out to anyone.
Don't give up hope my dear, stay in school as it will pay off in the long run. When I was in school, I found myself depressed often, usually I hadn't been doing what I needed to be doing,then I felt worse for not doing it. It's a vicious cycle, you don't feel like doing anything, then you don't do what you need to be doing then you feel worse for not doing what you are supposed to be doing. This can go on and on. May I suggest you make a List of Accomplishments. Get a piece of paper, and at the head, write list of Accomplishments. Each time you accomplish something, anything, big or small put it on your accomplishment list. Every day as you add things to your list of accomplishments, you will feel better as you accomplished something. Just putting something on your list is an accomplishment. Going to class today is an accomplishment. Getting up and getting dressed is an accomplishment. Posting on this page is an accomplishment. Just feel free to record big and small accomplishments on a daily basis. It doesn't have to be perfect, just that fact that you did something is an accompishment. Then as you look over your list you will see that you have done something, you have accomplished something, and you will feel better.
God bless and may the angels surround you with their love and protection.
