[Mismatched Socks]

I was diagnosed with mild anxiety a few weeks ago, though I guess I've always known I had it. It causes me a lot of stress, especially at night. I keep overthinking about things, which usually results in heart palpitations and sometimes even panic attacks. There was one night recently where I was up all night and felt absolutely terrible the next day. Luckily it was during the summer holidays so I didn't have college that day but it was still awful. I usually struggle for sleep at the weekend when I haven't been doing much. My dad told me it is because I am on my laptop quite late at night and I should come off at least an hour before I go to bed. I do try to spend less time online but when my friends are busy and don't want to meet up, there is really nothing else I can do. I sometimes take Nytol tablets to help me sleep but I often forget to take them and I don't want to become dependent on drugs. Are there any other ways I can help improve my sleep and stop overthinking at night?
