I'm scared to start therapy

Hey guys. So I don't know if I will or not,

But my friend tell me I should start therapy. I've had a couple full blown panic attacks this year as well as Just Uneven breathing and stress. I've also been getting really sad at night and feeling unworthy. They want me to start, but I'm really really scared. I dont know what to expect or how I can open up to a stranger. Can someone please tell me what it's like?

I'm still unsure. I just don't feel like i deserve to get better and I want my friends to be enough. They really love me.
