How to Stay Positive

I have been having a rough time lately. I feel a little better today after talking to my husband about everything, but I can't shake this sadness that is inside of me. I have been having a hard time feeling stuck in my current situation and trying to see the light at the end of the tunnel. My husband is better at seeing that light than I am. I just feel very overwhelmed with school work and not being able to have the time to help my son succeed. I am supposed to be a stay at home mom so that I can learn ASL quickly, spend time with Jacob, and do certain activities with him that therapists want me to do. Unfortunately, school has taken priority over almost everything. I would just quit school, but I have to stay in it to get money to help pay bills. I am so burned out on school right now that I don't even want to do it. But I have to. So I just feel really stuck right now emotionally and need to find a way to stay positive and "see the light". Anyone have any suggestions?
