Hey there StrawberryShortcake. I was browsing the threads so I feel I am here for a reason.
I was diagnosed with depression many many moons ago, so I do speak from experience!
I want to tell you something not many people understand. (I think in pictures - I am an artist so please bare with me).....You are on a ship. This ship is currently going through a storm. There is, believe it or not, a calm on the other side of the storm. In this storm, you experience helplessness, and worst of all, guilt for feeling helpless. You have to wait until the storm passes and the calm waters follow.
Translating for you: when you are really really down, and it feels like no one understand, or cares, or they get frustrated with you, just know that you will not feel like this much longer, because the feelings do eventually pass. It may take a week, then after that you suddenly hit an all time high, you see the light and you experience the calm waters. Until then, try and do the things that you feel like doing - read a book. Write in your journal. Go for a walk. Stay in your pj's the whole day. It's funny but people see a depressed person and feel obliged to tell them to get up, get dressed and pull yourself together. When people talk to me like that, I feel worse! My family knows now that I just need a little time and space and I will be okay soon. I do not neglect them or my chores, I just do it a little slower, in my PJ's.
My brother committed suicide when he was 29. He was four years older than me and we were very close. My entire family, including myself were all diagnosed with depression after he died. Chee...I wonder why? His death tore our family apart, we are still picking up the pieces, 15 years later, but praying hard and FAITH, HOPE AND LOVE in God gets us through. I lost my faith completely when my brother died, and it was the darkest, loneliest time in my life. When I came to my senses, I realised that I will never ever turn my back on God again, because He did wait for me on the other side of the storm. I also realised that He was the only one that could help me through it! I was also receiving counselling but at the end of the day, my hard earned lesson was that God knows best - not man. I also chucked my medication away because after a very long time on anti-depressants, it started having the opposite effect. Now please bare in mind, I am 41 and you are 18 - and I am no medical expert!!!!
So, firstly, weather the storm, it will pass. The calm WILL come.
Secondly, God loves you no matter what, "Footprints in the Sand" - Jesus will carry you through it!!!!
And thirdly, try and stop feeling guilty about being depressed! Yes, as believers in God, we are not to be depressed - is what 99% of Christians will tell you, but we are after all human, and life throws us storms all the time.
YOU ARE PRECIOUS AND IMPORTANT TO GOD. Do not lose faith in Him - the one and only that can get you through this storm. No matter what life throws at you, you can overcome it with His help.
He will rejoice with you on the other side of the storm. I pray the Lord Jesus sends you an Angel right now to give you one very monstrous hug. You are in my prayers StrawberryShortcake. If you ever feel like chatting, I am sure you will spot me somewhere.
I know your pain, I have traveled that path through the valley of darkness. But remember this, God is right there with you!! He will NOT leave you in the darkness. Please PM me whenever you want or need to talk. And please do read my story, I know it will help you too.
