Life isn't always as easy as it seems. While you may be having a wonderful day, there is a person who may be having an awful day and nothing seems to be going right. The best thing for you to do is help. Reach out a hand, offer advice, just be there. Help in every way you can because we are all on this crazy, eventful rollercoaster that we call life. So for the person who may be going through a rough time right now, this is for you.
It's okay to feel the way you are feeling. Feelings are a part of our emotions, and our emotions make up who we are. You wouldn't be yourself without feelings. Whatever you are going through, I'm sure it's not just an exaggeration or overreacting, like many people tend to conclude about someone in a bad mood. It's normal to not love life ever day because, face it, life doesn't always go as planned. Bad days are just part of it, and your feelings do matter. You are important. There are some people who do not have good support systems at home, so it is necessary for you to remember that you are important. I feel like sometimes people cannot understand where you are coming from when you share your feelings with them, and for this exact reason, my advice is to write a journal. I know what you're thinking, journal entries are so overrated and "I don't have a diary". Writing a journal doesn't have to be something that you keep up every day, just write whenever you're upset or angry. It will help you get a better understanding of the real reasons you are upset and may even help you get to the root of the problem so that it can be resolved. You can even write a letter to whomever you are conflicting with and just not send it. That always helps me.
So what if writing isn't for you? Well, I'd advise you to eat some ice cream or watch a movie. The best thing for you to do is take your mind off of the problem, that way you aren't constantly dwelling on it. If you continue to dwell on your problems, you'll most likely just make yourself more upset. When that mind starts going sometimes it doesn't know when to stop. So keep yourself busy. Sometimes it even helps to put everything on the "back burner" for a little while. If you give yourself the mentality that "I'll just handle it later", you can prepare yourself so that it won't bother you as much later on.
Don't let sadness or depression take over you. Remember who is in control. I know it may seem easier to let yourself go and let the pain and depression take over, but don't take the easy route. In time, your days will get better and things will get easier. Sometimes it's easier to just "Let go, and let God", if you turn to your religion for healing. Do things that bring you joy and happiness and don't surround yourself with negativity. Be with people who bring you up and ultimately bring out the best in you. There will always be someone that cares. Don't let the troubles and hard times get the best of you, look forward to the days ahead. And when you finally get there, you can look back and silently say to yourself, "I did it". You couldn't get to where you are today without yesterday.
