Go and do something with someone who's important to you. Don't let people push you. Don't be too self-assured..
Maybe you should pay a visit to your GP, he will be able to help you. Why don't you read a good book to relax or try to think about absolutely nothing. Unimportant things, which other people laugh away, you take way too seriously..
The mood swings you've been having lately may have been a bit too tiring. It's the right time to take your chances. Be yourself: you want people to love YOU, not an illusion..
You feel like you can't concentrate very well lately. Use that strength you're feeling, then all your efforts will pay off. If you're involved in trade, there is a good chance you'll have a lot of success..
