Insecurity is messing up my mentality

Ari

I honestly don’t know how to stop it anymore and it’s getting to the point where I’m ruining my own relationship and mentality(barley sleep at night sometimes). I remember when I was in school I would spent all of my part time job money on so much make up, clothing and hair just to feel truly accepted. If my social media wasn’t booming then I would feel like shit. I always needed attention just to be happy. Even though I’m not in school anymore and live with my boyfriend I just still feel like shit. Now that the expenses of life hits, I don’t exactly have the money anymore to make myself feel secure and it’s driving me to the point where I can’t even go on Instagram without crying after looking at a decent picture of a random girl. It’s eating me inside so much that I lash out on my boyfriend too often now and I know it’s not good but it’s hard for me to even talk about my feelings to anyone. I can’t even walk down the street with my head up because when I see someone that I know looks better than me I just start to break down crying in public. Dose anyone know a solution to this because it’s just fucking with my brain so bad. Am I mentally unstable?
