No one can read you mind to tell you what to do, to comfort you, no one is a wizard, life's not an anime people can have a sixth sense to just know exactually what you are feeling/going through, not even I know whats your specific situation is, but theres an universal advice i can give, that is to open up to SOMEONE, not ANYONE here on internet who you met in 3 seconds, someone you TRUST wont judge, someone you feel safe sharing your pain, or if you are able to, call the suicide hotline, or a therapist, just dont stay with it inside you, because this venom poisons you deep in the soul, and once the effect starts really showing the tool it took on you, it'll be too late to go back, so dont wait for this cup to overflow, share it wth someone, try to clear your mind through meditation, or any relaxation method, cause itll bring you some calmness, which i need you to use it to access this situation more deeply, with more sense.

Lets think about the way you've been thinking lately. was it mostly negative?do you blame yourself for things you've done in the past and regret it, even when it was something arguably small compared to other things?

Lets tru something new, first, try to relax to clear your mind, atleast weaken this overthinking, go on, take deep breaths, long exhales, the time you need, now, once you manage to regain more calmness, try to redirect your thoughts to other things, good things. I know, it seems Counterintuitive right now, to think of something positive when your days are so, so negative, and that may sound cliche(?) or something, but really try, try to look for the positive things, be grateful that you have friends, a house, food, that you have a life, because its truly the biggest blessing we receive in life, because to bypass death on our birth, to have this opportunity to meet people, to interact, to speak, it must be a gift, to make interact with more graceful beings like you, and i say graceful because you indeed have the love of God with you, the love of your friends, and cant you see it? Your friends value this fundamental thing, they value life, they value living, because there could have been so many things that could have gone wrong in life, life could be so, so worse, but it isnt. Yes, it could also be better, but if you were in the worst, wouldnt you think how great it would be to have a priviledged life, with coziness?

Get the things that are making you feel down, such as social media, specific friends, and other things (under your control), and try to ger away from them. Stop following those people you compare yourself to in Instagram, stop checking Twitter pages that only have hate and misinformation or crimeful posts, decrease your watch-time of news (dont be completly avoiding news, just know when its too much and when its affecting your health), anyways, try to do these small things, because with each baby step, youll get closer to your iminent glory, victory, to your bright light out of the tunnel
