Anyone been in this situation?

How do I do it? I need help.

I get alot of times that you should let yourself feel your emotions,now I kinda see the emotions i was struggling with before, and the problem might have been that i didnt let myself feel them, and i even think that thats why i experienced panic attacks. However im struggling again cause letting myself feel the emotions made me emotional and throughout the day many times i feel something that i dont know what to do with, giving them attention makes me spiral. Now its about my dog, for two days he vomitted out what he ate and now he doesnt want to eat his food, some food he does want but those are some human food that he shouldnt eat. But my mom brought chicken meat to him, he doesnt want to eat it, and she made something for him but he doesnt wants to eat that either...This makes me really sad cause im afraid i will lose him. I feel really bad when someone who i love is sick and with him its hard cause dogs cant tell you whats the problem. I have a deep sadness about it and fear and I let myself feel it but it gets so bad that it doesnt help me at all. I dont find it helpful, its just makes my day harder. Now again makes me angry if i hear someone saying you should feel all your feelings... Being aware of it, it takes your focus too, i never understood that, how you are aware of something and your focus does not move there... The bird exemple is not true for me, if i go out and hear a bird chirping either im aware of it and it takes my focus,or I enjoy it with the view, or I just notice it and then ignore it,I dont give so much attention to it. Right now birds are chirping, if i put my awarness there i notice them, but if i focus on here that im writing now, i dont notice them,i forget that birds are chirping...Its not like im aware of both... I agree that i should let myself feel more emotions cause alot of problems came there but I dont know where is the line and when im giving too much attention or when im dealing with them too much...

For 3 days I had a feeling that came up pretty often and I cant name it, I dont know what is it and the more i try to see what is it the more i feel worse. Usually letting feeling be and letting yourself experience it helps but not with this. I find myself feel grumpier, triggered and more angry. Its a mix of fear, but then i get angry too and I dont find letting myself experience it helpful cause I just stuck there. It feels like its in my chest and when it gets triggered it makes things hard to enjoy. I tried to be kind with myself and see what causes it but trying to be kind with myself triggers this annoying feeling and it just gets worse... i dont know what helps thats why i ask your help, if you ever experienced this... also i what i almlst forgot to mention, what is really important is that i became really sensitive to every thought, and any thought can trigger this feeling or any thought can trigger a negative feeling that will trigger this feeling. And honestly the "just accept it and let yourself feel what you feel" doesnt helps here cause i find myself really angry that i have to let myself feel the emotions that are triggered by these intrusive thoughts...
