How do I learn to just be myself

I've spent a lot of time just repressing things and only recently learned to be more selfish which kinda helped since I'm always so concerned about other people and not inconveniencing or impinging on them

I want to fully be myself but I literally shut down around other people and I can't help it I think I have literal PTSD

I'm panicking right now just having to go to the shop

Yo también comparto cierta similitudes. Yo he llegado al punto de incluso ser altruista. Realmente las personas se muestran agradecidas cuando les das una mano a veces en los momentos de más profunda necesidad.
Pero cuando lo haces constantemente, aunque no sea a la misma persona, las demás personas sienten que o tienes segundas intenciones con tus actos, o que simplemente estás desesperado por caer bien y / o ser aceptado.
Y no hay nada más patético para los demás que actuar de esta manera.
Muchas personas realmente se aprovechan de la gente débil de corazón.
Realmente ante los demás te hace ver como una persona sumisa, alguien que solo se deja pisotear o que puede aportar algo sin pedir nada a cambio (cómo pagarse las cervezas en una reunión de amigos).

A veces es mejor reflexionar seriamente cuando otra persona necesita una mano de ayuda, Y cuándo simplemente un consejo o lo que fuera. Porque como dicen: "si ayudas a alguien a hacer algo que puede hacerlo solo, no lo estás ayudando; lo haces inútil."
Es mejor reflexionar antes sobre nuestra propia integridad, y luego decidimos en quién confiar. A veces simplemente solo necesitas dejar que las demás personas resuelvan sus problemas por sí mismo. Porque probablemente a ti pocas veces te han ayudado.

I also share certain similarities. I have reached the point of even being altruistic. People are truly grateful when you give them a hand sometimes in times of deepest need.
But when you do it constantly, even if it's not to the same person, other people feel that you either have ulterior motives with your actions, or that you're simply desperate to be liked and /or accepted.
And there is nothing more pathetic to others than acting this way.
Many people really take advantage of weak-hearted people.
It really makes you look like a submissive person in front of others, someone who only allows themselves to be trampled on or who can contribute something without asking for anything in return (like paying for beers at a gathering of friends).

Sometimes it's better to seriously reflect when someone else needs a helping hand, and when just advice or whatever. Because as they say: "if you help someone do something they can do alone, you are not helping them; you make it useless."
It is better to first reflect on our own integrity, and then decide who to trust. Sometimes you just need to let other people solve their problems themselves. Because they have probably rarely helped you.

The first word of caution is to be aware that you can be yourself without being a recluse who doesn't care about others. Don't fall for undoing in your pursuit of being true to you, like many people who try to improve do.
Regarding others, you should keep in mind that your only obligations to be a good person towards those you care about is to; not intentionally cause harm to them, talk to them or hang out from time to time when you are free to do so, pick the path of least harm that still allows you to reach your goals, keep your promises, and provide support to the people you care about when they need you. Anything outside of these key things to maintaining relationships are not your responsibility and you are not on the hook for them. Having your own tastes, wants, likes, and needs have nothing to do with others and should not inconvenience them.
