I visited back home for the first time in almost 2 years recently and spent some real quality time with the family. My younger sister and I had long discussions about the past year because I know she had been struggling with uni/making friends/and feeling fatigued all the time. The feelings she was describing were very similar to those that I have been dealing with.
The reason I went home was to see her graduation. She has said that my constant Skyping and listening to her problems and giving her motivation throughout the year is what got her through. Just a few things I kept telling her to help cope:
1. Avoid coffee and black tea. Stick to Green Tea/Roobios/Herbal Teas
2. Exercise, specifically cardio (running) in the morning.
3. Listening to positive music
4. Force yourself to get up an hour early, and going to bed early at the other end.
5. No TV/Internet within the last hour or so of bed. Read a book and stay away from screens
6. Stay in contact with friends/family with a text, even if it's just a quick hello/how are you through the day? Any contact is worthwhile.
7. Stay off Facebook/comparing yourself to what others are doing or how happy they seem to be. We are all alone really and worry at times but no-one talks about it on there, everyone is out doing something more fun than you or achieving something.
8. Read more/Watch less TV
9. Limit alcohol.
I used to think that the last one was the solution to all my problems. But in truth, by not attending social events, I was compounding my anxiety. It's a constant battle but I love catching up with good friends and having a beer. It's important to realise early that not everyone is worthwhile getting drunk for!
My older sister was diagnosed with a version of schizophrenia and has been living with it for years now so I sometimes wonder if we just have fucked up genes. I'm convinced though, that for young people these days it's more prevalent than ever. I even seen people handing out leaflets outside train stations for it when I was at home for anxiety help lines. Maybe life is so easy these days that we don't fear for our lives like in wartime but we fear for EVERYTHING else.
I have no experience with meds but I'm sure others will be better at giving advice, and good luck to your daughter in the year ahead, I have total faith she will get through with your support and understanding. We all do in the end!
