Some short term things that help me are:
•Drawing. It can either be on paper or digitally, but for me, paper works better.
•Listening to music. I like music that is more energetic. I really enjoy rock and I also like dubstep and trap. It makes me feel more at ease if I’m feeling stressed, too.
•Watching funny stuff on YouTube. I also watch cute cat and animal videos when I feel horrible. It helps a LOT for me.
•Talk to my friends. I haven’t told anyone (apart from this site) that I’m suicidal, but even talking to my friends and (sometimes) forcing myself out of the house when I’m especially terrible makes me feel way better.
•and on the contrary, being alone. Sometimes I just like to do all of the things above alone in my room, maybe wrapped in a blanket.
Some long term things that help me are:
•Spending time with my family and friends. I know that I already listed that in my “short term” list, but I was mostly talking about when I feel more bad than usual.
•Buying a new video game, new poster, new anime figure, new headphones, etc. It makes me want to be invested in the thing that I bought for a long time.
•Pets or animals. I’m more of a dog person, if I’m being honest. Having a pet that loves you, no matter what the pet is, is amazing and makes me happy.
...I can’t think of anything more right now, but there’s deffinitely more! I might update this later.
