Overthinking. I just want to be okay

It happens all the time. Whether im trying to write a story or getting scolded, i always overthink about everything and anything. Its hard to even put it into writing because well, i have too much stuff going on in my head and it hurts. To the point where i have anxieties, and recently whenever something triggers a memory or something im sensitive to in the past, i cry myself to sleep. And when i do there are times when i feel like im suffocating and drowning under my tears and frustrations and problems, i just want to breathe. And i know that there are more people whos going through worse experiences than me. So i often ask myself 'Do i even have the right to feel this lonely?' I just want to be okay
