I can only offer words, even though words can only do so much to soothe your pain. You have doubts and you feel low but I share with you this:

“I care not so much what I am to others as what I am to myself. I will be rich by myself, and not by borrowing.”

Your self-worth is intrinsically yours to decide; you are more deserving of the good things than you think.

Throw away the baggage of old and treat whatever comes next as a blank canvas. Step back and realise that this is nothing in the bigger scheme of things - life inevitably moves on and you still have ppl by your side who truly loves you.
