I am facing the same sickness since last 5 years ago. I know how badly you wanted to help yourself. It is a good thing when you realized that you're suffering from dysania then anyone could notice it. Usually, dysania occurs cause of depression. You feel of losing an excitement to carry on your daily routine.
I refused to go for any counselling cause I know I can help myself than anyone. Based on my own experience, it is not easy but it is worth to help your own self cause nobody can help you except 'you'. At first, I choose not to eat any drugs to help me. Most of the therapist will suggest you these easier ways. Don't! For long run it can give you side effects or you might depend on it. Focus on healing yourself in a natural way. First, you have to tell yourself "you need to help yourself to get up". Set an alarm 1 hour earlier or 2 hours earlier.
Try to sleep early, so you can get enough sleep at least 7-8 hours a day. Nobody can really understand how you feeling this way except people who face the same dysania like you do. I understand how badly you need someone to help you to get up, it feels like you lose motivation and you feel to be in bed is more comfortable than any places. Try to set your goal in life, it is ok to create life goals whenever you think you need to adjust something about your life. When you have a life direction it will help you to get excitement to get it, if possible your life goal is "to yourself". Your happiness not in anyone else's hand, it's on you. Try to love yourself, put yourself first than anyone else first. Feel a little pity for yourself, enough be so hard to yourself forgive you. This the remedy.
Last 5 years ago I slept almost 13 hours or more every day until my ex GF gave up on me, I lost my job and finally she dumped me. I was suffering for dysania until last 2 years ago. One day I seek for help, same like you did. But nobody can really understand it well than me. So I try to find a way, I struggle for 17 months to put myself together. Usually, there's a major reason that "kill inner self", until you lose all your excitement in life that makes you not to get up, you feel the dream is better than staying awake. At this point, you missed many things in life. You losing a great time and many things that you need to fix and hard to give an attention to people who needing you. If this continues to happen, you going to put yourself in trouble.
Life has to go on. Like I said nobody can help you except "you". Stop feeling depressed, sometimes you are the bigger enemy to yourselves. Before you ever make the first step, whenever you feel demotivated. You have to find a way to motivate yourself. Control your emotion. You need to change this, by doing exercise as your daily routine it really can help you to carry your daily routine. Not just you'll feel good about yourself but it helps to make your life healthier.
Try not to take any alcohol, sweet stuff or too much caffeine. You need to have a discipline. I trained myself to get up every day at 6.30am to jog for an hour before going work. I write a new goal in my life, it never is late. Make sure your goal is about you. My goal is to get my Doctorate and I have to make sure I'll get it. That's a reason I get up every day. For almost 3 years now I helping myself in natural ways, no drugs were taken but just motivation to help me to make it better. Every time I feel demotivated, I will find a motivation video to boost myself mood.
Once a month I go for a vacation alone to places I never been, it's good to get a little break and treat yourself well. When you feel lonely, call whoever you feel like to talk to. Keep in touch with your surrounding, don't be a hermit. Enjoy see sunset or sunrise, you will feel grateful for still be alive. When you feel lonely is not the biggest problem, it just a feeling that you can ignore and do something you like by yourself. You at your freedom, how good life to offer. Sometimes it is good to have a "Me time" at least 1 hour everyday. Get out from your house and go explore the world. So many great things to do. Take it step by step. Focus on your daily progress. Forget whatever that hurts you. Life is too short. So waste it wisely. I hope this can help you, my friend. Get up, go get what you want. Don't let it "kill you slowly", you have to help yourself. Now I get what I dream, I finished my study, I met someone new and I having my own business. I talked based on my experience. So, it is not too late to do the very best things for yourself now. May god bless you! Go get it, Tiger!
