anxiety, texting, boundaries. help plz.

hi.

i don't really know why i'm here, if i'm being honest. i don't want to bother anyone close to me, i guess. plus, it feels like such a stupid thing to struggle about right now... idk.

i broke up with someone a few weeks ago. it was messy, but i made it out and did as much damage control as possible -which was,,, hard. i panicked, went into a downward spiral and all that jazz... some of you certainly know the feeling. anyway. i had moved on already, and i over them. completely. that's not the issue.
but they came back a week ago, to ask me how i was doing and for my address so they can send me something/stuff. and i just... i panicked? i still do? it freaks me out and exhausts me to text people so it was already difficult, but it just got worse. i left them on read a week ago and i have no idea what to say because it feels like the more time passes, the worse it is. i don't know how to say no and i have an anxiety attack/am on the verge of tears every time i try to answer, and it's horrible because it feels like my overreacting but i have no control over it?

lately my anxiety(&depression) has been getting worse, and i'm so scared of alarming others that i either put on a mask, sleep or stay in my room. texting and even just talking is bad, with everyone. i say random #######4 and then go through breakdowns throughout the day. i'm shaking all the time, my heart beats so fast all the time too. everything is too much and i go into overdrive for the tiniest things. i don't know what to do.

i don't know what to do, i feel like i'm about to explode

Well it kind of sounds like you are dealing with quite a bit. I think you are the only person who can truly know the real you but likely if others knew they would totally be ok with you doing what you need to do to take care of yourself.

I can tell you that if you were anyone in my circles, my family etc... that I would definitely want to be helpful and I would really want to know so I could do my best to be helpful. Its not a burden to help people who are important so I'd really encourage you to talk to a parent or sibling or close friend that you think may be helpful.

I wish you the best and hope things get better soon.
