Hey! I understand you most of the situations. I also lost my grandpa it's been 3 months and i am having a very hard time. Today i also had a dream about my dad who found out i was self harming.
That was a thing that i would never want to happend in real life. I also have a lot of nightmares. What i wanna say is that you are not alone. And about putting others first is a good thing but not to do it too much. You need to take care of yourself first. If you feel like you don't wanna do that anymore i think that it's time for you to say to them :- sorry, but i think you should understand that i'm always the therapist and I can't go on anymore . Ik it may sound rude but it's the truth after all. I really don't wanna seem rude but your friend's need to understand right? And ik it may sound absurd but you may need sleep. Make sure to clear your mind and say to yourself : im ok, everything will be fine and stay positive. Ik life it's hard but we all need to fight . Everything will get better soon believe me . It sounds forever but the happiness will start to show up soon. I wish all the best for you 😊
