progress

why is the process of getting through trauma so hard? i have a 1 time near death trauma that just left me with anxiety and ptsd and even though i have made so much progress it still feels so hard sometimes. i can do so much more now than i could before but i feel so lost sometimes. it feels really lonely and i am still so scared to travel and feel so anxious going new places by myself and random stuff like that. i have a really supportive family, friends, and boyfriend which is amazing but i still feel so alone and stuck sometimes. i just wanna know that it gets easier and my triggers will ease up eventually?
